Velociraptors really aren't worth the money, ask your uncle if he wants a fast boot up and programs loading faster. If he says yes, either get an SSD or two WDCB 1TB and run them in RAID0. The XIGMATEK Dark Knight is a quality heatsink for cheap, if you want something bigger go for the TRUE or Noctua NH-U12P
Consider downgrading to a GTX 275, you will see a few FPS difference between the cards. If you plan on sli in the future with a GTX 275, you could also downgrade to a 750TX. Change the ram to OCZ Platinum since you will be overclocking.
Also change the case to a HAF 932 just to be sure you have plenty of space.
If you read the reviews on newegg and the profesional ones on that link up above you will find that Scout is small, and I don't think it will be a good choice for SLI which I'm guessing you plan on doing with that 850w psu in your build.
If SLI is in the future I would seriously look at this case down below. Get a can of flat black high temp spray paint and a roll of masking tape at walmart, home depot, lowes etc...and it takes all of a few minutes to paint the inside of this 922 HAF...which will fit those cards in SLI and it's smaller than the 932 HAF.
Although it doesnt have the unessisary raptor, if you still want the VRaptor you cant get this build. It is cheaper(not by to much but it is) then the one you have, but the video card is better then the one you chose.
And you can go back to the 800w PSU to save money, and get like a CPU cooler i just went with a lower rating 750w because its modular.
Sounds good people. The case was definitely a swinging point for me. When he comes down Thursday I'll go through some of the cases he can get so he can choose which one he likes. He might end up getting a full tower case, who knows =P
I have the HAF and wouldn't trade it. It's got great airflow, TONS of room, nice cable management, and it's unbelievably quiet. Don't know about the computer desk situation, but it won't fit in the tower cabinet. Mine sits next to my feet and almost touches my keyboard.
Yep, I also have the Coolermaster HAF 932, and I love it. Of course when I got it I painted the inside black right away, but other than that, it is great. I love the cable management system, and the CPU tray hole so you can add a good CPU cooler without taking the MB off. When he comes down I was going to suggest that one first anyways.
Only gripe about it would be cleaning the mesh, which can get dusty pretty quick, also the lack of air filters.
