Need help with a new rig

[Nick624]

After having the same computer for five years, never even once upgrading it, and thinking it was fine for gamng was a mistake. So, instead of buying a retail computer i was thinking of building my own. This is going to be for high end gaming (Crysis anyone? :P). My budget is about 3.5 grand to 5 grand. (I've been working hard for the past two years. So far, I've picked out almost all the parts that i will need. It's an intel based system with SLI capabilities.

CPU: Intel Core 2 Extreme QX6850 3.0GHz
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3241533&CatId=2399
GPU: EVGA GeForce 8800 Ultra KO Video Card + XFX GeForce 8800 Ultra Video Card
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3094314&sku=P450-8800
And http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3187832&sku=E145-8806
Motherboard: XFX nForce 680i SLI NVIDIA Socket 775 ATX Motherboard
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=2959596&sku=P450-9104
Hard Drive: Seagate Barracuda ES 500GB Hard Drive - 7200, 16MB, SATA-300, OEM
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3241601&sku=TSD-500NS
RAM: OCZ Reaper HPC Dual Channel 2048MB PC9200 DDR2 1150MHz Memory (2 x 1024MB)
http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3079599&sku=O261-7058

The peripherals are already taken care of/

Altough i have a few questions. First off, i was thinking of installing liquid cooling, but this is going to be my first build, and I don't think i want to ruin a PC just for it. Also, my parents are divorced, so i move from my fathers house to my mothers every 2nd week. Would i have to drain the liquid any time i need to travel with it (About 5-10KM). It's also because of this I'm not sure if I should go with a full size case or a mid size one. That's about it, any comments or suggestions would be appreciated.

If I was going to spend that kind of money, I'd wait a few more weeks, or until the first of the year, when all of the X38 chipset stuff is finally out.
Skip the 680- go with an INTEL chipset.
Unless you are totally under the gun to build a new system.

The X38 does not perform any better than the P35. If you have your heart set on SLI, the 680i is the best game in town, but you should order 2 *IDENTICAL* video cards and find a different brand of motherboard than XFX, think Asus Striker. You should also get a Barracuda .10 or .11, not a ES, the ES is a drive designed for servers, not workstations. I'd also go for more mainstream DDR2-800 ram, that hotrod stuff really won't make a noticeable difference. Stick with quality air cooling if you are going to be transporting the computer frequently. Make sure you have a quality brand certified power supply.
