Home built computer help

[geovoni]

So, I decided to buy a new computer game but after looking at them, at Best Buy, I realized that my laptop couldn't play, really, any of the games there. I knew that I couldn't get a new computer, so dad suggested for me to build my own computer. So I did some research and educated myself on computer technical speak, what I needed and where to look for my parts.
Yesterday, dad said that you might be able to help me.
I don't want to waste my money, so I was wondering if you could tell me if there are any flaws in my parts that I choose, mainly compatibility problems.
I was also wondering if you knew of any other places / websites to buy parts. To date, I have been using newegg.com, I also looked at tigerdirect.com but found that newegg sold the same parts, cheaper. I have a very tight budget, only about 400 dollars, and cheaper is always better (as long as the part works, consistently).

So here are the parts I choose and the links to their respective information.

I think that's all the parts I need.
I'm definitely looking to save money where I can and I don't care as much for sound as I do for graphics. So I thought that a sound card on my motherboard would suffice.
I know that my case might look to extravagant for my budget but I found that, with the on board power supply, it was cheaper than buying them separate. My information sources (a tutorial from the web) said that a 500 watt, or volt??, power supply would be enough but I just want to make sure that that is a reasonable amount.
I am building this computer to play games, not the best, newest games but a reasonable number of good games.
I also have upgrade ability in mind; I don't want my motherboard to hold me back from upgrading when I can just choose a different one right now.
So it would be nice if you could just point out any flaws, cheap improvements, compatibility problems, or simple upgrade ability changes, to make sure I am on the right track.
Thank you.

The power supply that comes with that case is not good.

Look at this combo: http://www.newegg.com/Product/Produc...82E16811129024

I don't know amd processors or motherboards, so I'll leave that to others.

And that video card isn't going to cut it for gaming. You would need to get something better.

$400 is a low budget for a build, especially a gaming build. If you could probably get a fewhundred more then it would be a lot more doable.

Do you have monitor, keyboard, mouse, speakers, and operating system?

[geovoni]

yes I have a monitor, mouse, keyboard, and OS.... all that stuff. Im going to use XP.

This is probably the lowest I would go for a gaming build video card:

I dont think that case will work with my motherboard cuz my mobo is Micro ATX and your case is just ATX will my mobo still work?

[shadowpr]

As far as I know an ATX case will fit atx motherboards and micro atx motherboards.

[geovoni]

emk... Ill do some research. thanks for the help!!

[geovoni]

Yes most of the time a Micro ATX motherboard will work with an ATX case.... but not the other way around.

Why isint my power source good?

Apevia brand power supplies are known to not provide good power. They fail under load, and can destroy other parts when they die.
