Case: I use the
HAF932. I also really like this case:
Corsair 800D
CPU: The i7 920 is a great processor.
CPU Cooling: I use a CoolerMaster v8. Keeps my AMD Phenom IIx4 945 at ~26C idle (~35C load), the 125w edition (versus the 95w).
Motherboard: The
Asus P6T seems to be the favorite motherboard of many. I personally prefer MSI. Pick your poison.
RAM: G.Skill or Corsair, I also wouldn't suggest OCZ their RAM gives me nightmares. Pain in the butt to set up correctly in the BIOS it comes set to 1066 and you have to get the timings and voltages right to get it at 1600 I was a frequent in their forum trying to figure it all out.
PSU: I recommend this bad boy.
ThermalTake BlackWidow
HDD: I prefer Western Digital over all HDD companies. I have a 10 year old 32GB ATA drive from WD that still works.
GPU: ATI runs hotter than Nividia. Each has its perks. I like the GTS250 in SLI others would disagree. The ATI 5800 series is also a really good choice. You could also get away with the 5770 in CrossFire.
Optical Drive: Lite-On is my company of choice.
Sound Card: Creative SoundBlaster FTW. AVOID RealTek their sound cards have issues.
Wireless Card: Not much choice from what I was looking at. Rosewill was the only name I recognized.
