It is increasingly popular to build your own computer. In most cases, it saves money, and it guarantees you get what you want. It also assures you avoid proprietary designs many companies use to keep you coming to them for new parts. Best of all, having built the system yourself, you become very familiar with that system and with computers in general.

People from all walks of life today build their own PCs. Executives, engineers, students, housewives, they all do it today. But, at the same time, pre-built PCs have come down in price quite a bit. Today, one is left to wonder whether it is best to build a PC yourself or to simply buy one off the shelf. I’ll address that here.

If you are a real PC enthusiast, this question may be a non-issue. The answer may be as obvious as the color of the sky. This is predictable, of course. When one builds their own PC, they are able to not only understand their PC better because they built it, but they are able to choose each component that goes into their PC. There is really something to be said for choosing your own components, and I’ll go into that further below. There is also a certain sense of satisfaction with having built a PC. One spends a few hours (or less for those more familiar with the process) to put the thing together. Then comes the moment of truth when one hits the power switch for the first time. If it works on the first try, its beer time!

But, besides the joy of it, is it worth it? Is it a practical use of your time? Will it really save you money? The answer to that question today has become a bit gray. A few years ago, the answer was obvious. Pre-built PCs were typically built from OEM, cheap components. The performance was average to simply awful. The choice was obvious: If you wanted a decent PC, you better build it. Today, the line has blurred. Where many off-the-shelf PCs today still use cheaper components in an effort to save money, there are more pre-built PCs today which do use quality hardware and whose performance ranks up there with the best of them.

Let us look at some of the key areas of interest in this:

Component Selection

Most commercial PC buyers (except for the ones who build higher end models) do not make a big deal of which components they use. They will, of course, tell you the specs of the system, but often do not elaborate on the brands of the equipment they use. Most lower to average priced pre-built PCs use more or less generic hardware. It gets the job done, but what you get is what you get. Upgrading can be a problem for this reason. In contrast, building your own PC means you can handpick all components in your system. You can ensure you get good, name brand hardware which will have proper manufacturer support and driver support. Most importantly, you can ensure you get hardware that will perform. One aspect of pre-built is that compatibility issues are taken care of by the manufacturer, but there is a tradeoff made in that guarantee.

Price

In general, you can get more bang for your buck building your own PC. In many cases, you will find equally priced and comparable PCs, where one is pre-built and one would be homebuilt. You can buy PCs cheaper than you can build them, but when you consider the hardware choices within, the price is offset in favor of homebuilt. One thing to consider here is the value of your time. If you are a very busy person where time is money, then you most likely want to buy a pre-built PC. If you don’t mind taking the time, though, you can do better doing it yourself.

Support

Available support is a key concern for do-it-yourselfers. When you build it yourself, there is nowhere to take the PC for service. You can’t say “Here, make this work.” On the other hand, pre-built machines typically do come with manufacturer support. But, support is anything but consistent. Some manufacturers have questionable records on support whereas some are quite good at it. Having support for your PC is no guarantee of having a problem-free user experience, and it is certainly no guarantee that they will take responsibility for your PC if it doesn’t work. The good news for do-it-yourselfers is that the community of people who do this kind of thing themselves is increasing. There is a lot of data on the internet, and community sources for assistance. I’m compelled to mention our own forums where a community of thousands is available to help you out on your PC.

Warranty

On pre-built PCs, there is typically a warranty on the whole system, and in many instances, you are offered an extended service plan at the time of purchase. Home built PCs do not have full system warranties, of course, but if you buy good name brand hardware, most of the components will themselves have warranties. So, really, either way, you can be covered here.

Software

Pre-built PCs often come with much software on it, most importantly the operating system itself. The actual price of the software is pretty good, because manufacturers get great deals on this software because they buy in bulk. On the flip side, though, these PCs sometimes come with too much software, meaning garbage that you do not want and just clutters the hard drive and bugs you to buy stuff. It can be quite annoying. On homebuilt PCs, you might pay a little more for the software per unit, but you will get what you want and only what you want, plus you can set it up how you want.

In general, I’m a big fan of the homebuilt PC. I’ve never used a PC I didn’t build myself. I think its a huge money saver. In my case, I built it myself, and then as technology progressed, I incrementally upgraded the machine. This saves a lot of money in the long run, because with a pre-built commercial machine, once it goes out of date, you pretty much need to start anew with a new PC.

    So I know next to nothing about the inner workings of a pc but I like to think I am smart enough to figure it out with a little help so here is my situation. I have an old slow laptop and have been looking at a new one for ages and nothing I have seen off the shelf has fit the script. What I want is pretty basic alot of memory for music, speed and a DVD or possibly blu Ray player. Thank you in advance to anyone who responds

        “Hey, buy this and this and this, and make your PC $500 more expensive. It’s all the same things, but it performs better!”

        He’s obviously looking for a cheap custom build… You’re trying to get him to buy overly expensive and way overperforming items for what he probably needs.

        • listen! says:

          omg what is wrong with you? here is the major rule everyone! should follow.
          1. if the computer you are buying is less than $500 then buy it
          2. if the computer you are buying is more than $500 then build it
          of course this can vary a little and use common sense but for the most part this rule works

    • You’ll definitely need to upgrade that PSU. Any PSU under $80 can not possibly be reliable. The PSU is probably the most important part of this computer if you want it to last.

      why would you ever want a floppy drive? can you even still buy floppy disks? get a dvd burner at least

      • lou says:

        I still have a floppy and play astroeids,I go back to comodore 64 systems ,re: these are old but still fun,My Systems i rebuild evry 5-6 years and it IS getting harder to find mobo`s that have IDE `s for them as the newer mobos only have 1 slot for an IDE now what do you think they have 1 slot for an IDE for ?Because the manufacturer knows there are still alot of floppy users like myself,By the way my floppy is the 2.44MB type try to replace that.almost immpossible.Happy PCin

    Good article, but there’s one gloss-over however.

    Re Software/OS, one can install an opensource OS such as Ubuntu and save having to pay window tax to King William of Redmond! This surely results in quite some saving, and could make the world a better place.

  4. Bigbk92 says:

    Hi guys I have a question for you. I was wondering if there was a way i could Burn 2 DVD at once. My old PC i had years ago couldnt do. Maybe because it was some crap i bought from Best Buy p4 processor with little to memory. Well now i built my own pc and since I store a lot of movies I was thinking about buying my second burner and another hard drive. I think i may pull off the double burn with out lag if I have each DVD being riped/burnt to seperate hard drives. Will this work with out lag or damage? I have 8 gigs of ramm, a 2.33 quad processor, EVGA 132-CK-NF78-A1 LGA 775 NVIDIA nForce 780i SLI ATX Intel Motherboard, 750 power supply, 9800 evga gpu,. Think it can work or is there another way?

  5. Thocrun says:

    any ideas on how to build your own PC server for internet games? I think that’ll be a lot more usefull then building a personal pc unless you want to run something extreme. but I don’t know how exactly to go about it, I have no real size limitation, just want it reliable, I’m thinking I would probably run Linux if they offer a OS like that for servers, but yeah, I’m not talking about google or anything, just enough to run a game that could accomadate maybe up to 40 ppl at a time (could probably spend some of the time in a power outage working on it) , I know internet speed will probably become an issue, but I think that setting up the “server” before would be better then getting the internet speed I want first and then know that I have to pay the bill, but still have no way to pay it (Worst Case Scenario-probably). I would like step by step instructions for that, then once I learn pc programming I could probably get a team and make the game or whatever, haven’t really figured out any uses for one besides hosting e-mail or game “server” (idk what exactly to call it), there has to be more uses then that it would be a good thing to have on a website someplace, :( just sad I haven’t found that website yet lol

    • Mike says:

      Builder a server itself isn’t that complicated but if you actually want to host web space / emails or games from internet users it’s going to cost you. You can’t regularly hook up a home-made server to your existing internet connection without crappy bandwidth issues to a non-dedicated line. A call to your ISP to let them know you have a server and see what rates they’re going to charge you is pretty much the first step.

      So if you wanted to shell out X dollars per month hosting without charging your users for a password or some heavy banner advertisements, thanks for the free play. Just keep in time that home made servers can be finicky, SOBS, and need maintenance from time to time. So be prepared to troubleshoot and internal or TCP/IP problems that will surely crop up after a little while if not immediately.

      Most people build home servers for the purpose of dumping their networks into them either as backup or just another storage area where they can more quickly share between all connected computers/gadgets in the home, particularly home entertainment centers.

      • Thocrun says:

        Well I was actually planning on programming my own game, but idk anything about programming at the moment so I think I’ll be looking for some programmer to help me with either java C/C++, maybe even the new java fx but yeah, I’ll need a reliable connection, wasn’t going to make a game for money though so I really don’t care if the connection is slow just has to be reliable, I know that best buy had a hp with 6 RAM and 640 hard drive for $600 dollars if anybody wants a really high performer and has the money I’d check that out. yeah, I am going to take a computer class out to my local career center so that class should help me a bit on the hardware, just need someone that knows java se or something like that.

    I think I just found a link to it on this site lol

  7. jake says:

    i am looking to build my first desktop, and i have no idea where to start. i am familiar with how to actully put it together, but as far as equipment goes, i don’t know what is compatible. like what processors and graphics cards work with what mother boards or does it not matter?

    • Ldouble_e says:

      Jake,
      There are some good sites about building if you spend some time looking. Anyway, for the mother board and CPU you will want dual core or better. I suggest dual core because it is fully utilized by some games where quad is not utilized by any games. Then you need to get a mother board to match it. You need to check three things for sure. 1. The cpu socket type (LGA 775, LGA 1366 intel and AM2, AM2+, AM3 for AMD) matches the sockect type supported by the motherboard. 2. You want to make sure the board will fit in you case. The most common form factors are ATX and miniATX, but there are others like BTX out there. Your best bet is to look for a case that supports both ATX and miniATX. If worst came to worst you could always drill a hole but thats what you want to avoid. (Tip..there are brass looking nuts that come with the board, they are spacers and are very import so don’t forget to install them)
      3. You want to check your FSB or Front side bus. Your CPU, mobo, and RAM will all have a FSB listed. Your new rig will only run as fast as the smallest FSB. So if your CPU and mobo are 1333mhz FSB and you get ram that is 800Mhz, then your system will only be as fast as an 800MHz set up. All the speed will bottle neck at the ram. You don’t need to match all three just be aware of it. I run a 1333Mhz mobo, 1666 CPU and 1060 Ram for an example so I’m at 1066MHz tops for data transfer speeds. GPU you will want Nvidia on an intel and ATI on an AMD just because they are better supported on by their own chipset or north bridge. For Ram check the mother boards QVL or qualified vendors list. IT should be in the mobo manual on the manufacturers website as a pdf file. Power supply should be at least 550Watts or better depending on which GPU you will buy. They require a PCIeX16 slot and there own power rail from the PSU. The newer GPU’s even require two power rails. Your minimum wattage will be what the CPU consumes plus the GPU and then add 50 watts. Don’t go cheap on the PSU it is really import and a bad one will cause system faults that may take months to figure out it’s the PSU and not the computer. Hard drive should be 7200 RPM and SATA at a minimum. CD/DVD roms are up to you, look for higher cache 32Mb units. Good luck and try http://www.newegg.com they have really good deals along with customer ratings and comments so you can get an idea if a part may have an issue with another peice of hardware etc.

      • Jhampa says:

        I read your suggestions and I am in the same category as Jake. If you had the time could you put together a list of components? I know this might be a lot but compatibility is important (I am told) and I would hate to spend the money and find I blew it on matching up things. I will print out your suggestions. Obviously needs lots of research to make it all match.

  13. Jack says:

    I wouldn’t recommend building your own PC. If you do ANYTHING wrong, you’ll end up frying your motherboard and possibly CPU. If you’ve ever tried debugging software, imagine there is a $300 dollar penatly every time you mess up and you have to wait 4 days to try again (get new parts).

    • brad says:

      That is why you practice on your old computers so you can get good enough to build a new one. If you keep frying your parts, try grounding yourself.

    hello I need some help. I am in the process of building a computer, but i am not sure of which parts to get exactly. I am going to be doing some video editing, and i will be storing a lot of music and movies on it, along with burning dvds and cds. So far, i have an ATX mid tower. i was gonna wait to buy it until i knew all the parts i was gong to get, but the website was switching owners so i was able to get the $60 case with a 400w psu for about $17. so i jumped on it. other than that, i think im going to get an AMD phenom II 3.1GHz callisto cpu. if anyone could give me some tips about which mobo, memory, and HD to get, i would greatly appreciate it. and also which cd/dvd drives to get, cause the whole cd/dvd-r+w-rw+rw+-rw+-r x24 burner litescribe whatever confuses the hell out of me. THANK YOU for any help.

    P.S The psu that came with the case is an LIC 400BTX…..is it ok for my kind of setup? i wont be doing any gaming or extreme overclocking, so i wont need too much power….right?

    • harveydenT says:

      Wait a second….. i just realized i have a btx psu in an atx case…what the hell? isnt that a completely different case type?

    I really hope you can be more help to me than the last few people on the forums I’ve spoken with-they were all very rude to me and did not specify what I needed to do. Here is my problem:I had a laptop that worked awesome, regardless of what others would say..I’m a simmer, so I had all my Sims 2 games and Sims 3 installed at once and had no problems until suddenly one day these crazy static bars kept coming across my screen, it was nuts! I showed my fiance and he said the repairs would probably cost more than the laptop itself, so we put it away for future repairs and went out and bought a desktop pc-an emachine.

    Today I went to the site Canyourunit, and the scan basically told me that my RAM and CPU speed were not up to the requirements to play Sims 3. I was so upset I wanted to cry! The games themselves are very expensive for one, and the computer already cost us around $300. I went to a forum for help, the people there said that also my graphics card isn’t good enough. They suggested that I buy a barebone kit from Newegg or TigerDirect online. But I have no idea at all which one to buy!!! I have no clue if the barebone kit must be compatible with my computer or what! I was also told I’ll need a new cooler and power supply. If you need me to, I can give you my full dxdiag as well as the system requirements for Sims 3..The first expansion pack for Sims 3 will be out in November and I’m praying I can figure all this out by then and be ready to play my games. :( I’ve searched and searched and all the info on the barebones kits look like Greek to me! lol What I want is to purchase a barebones kit (and anything else I may need) that will make it so that I don’t have to ever worry that my computer cannot meet the requirements for Sims games again. Can you please give me some advice? Do you know of just the right barebone kit for me and just how much I’m looking at spending? I have so many questions it’s making my head spin..I just have no clue where to start, and I feel really hopeless. All I want is to enjoy this game that I paid hard-earned money for with no issues!! Please help?

      If you want to build a cheap effective desktop. (Cheap here)
      Go to a web site like geeks.com, tigerderict, or even amazon
      find a tower with a power supply.(though you will have to replace the power supply with in a year
      Buy a wolfdale e5200 core dual 65 dollars (later you can bsel mod to a 3.3mhz)
      look at the compatible motherboard size m-atx or atx those are sizes atx being the largest
      And compatible to dual cores.
      Asus and foxconns are pretty reliable. You want a 4 connection memory supply (4 memory banks)
      Buy 2-4 gigs of 1gig ram average $15-$20 a gig when bought in packs ddr2 most likely
      A nice graphics card not to expensive like a 4600 series ati.(around 50-60)
      And a hard drive of your choice.(coast around 50-200 dollars depends on size.)
      And a dvd player or dvd burner(their pretty cheap now a days 30-40 dollars.
      and for you don’t have and snags
      also buy
      a 120 mm($10)
      fan 80 mm fan ($10)
      if heatsink isn’t included with cpu (wolfdale) a heat sink for 775 socket ($15-$20)
      2-3 molex adapter $2 a piece
      maybe a few sata cables just in case $1-$5 a piece

      IF Thats TO Much TO START TRY A BARE BONES GET THEN JUST ADD HARD DRIVE AND VIDEO CARD
