CPU: i7 920
Good price, can be OC'd to 4.0Ghz
Motherboard: ASUS P6T Deluxe V2
Lots of USB ports, good manual, easy BIOS
OS: Windows Vista Home Premium 32 bit
Will replace with Seven in October; not as clumsy, slow, and evil as feared, but still ... eh.
PSU: CORSAIR 1000w HX Series 12v ATX SLI Ready 80 Plus Certified Power Supply - CMPSU-1000HX
Rock solid, excellent components, semi-modular, good selection of long-enough cables. Uhh, pricy.
Optical Drive: Samsung SH-S223Q Supermulti SATA 22X Lightscribe DVD-Writable Drive
Good price, good performance, good looking ... well, not ugly.
CPU Cooler: CoolIT DM-1000 Domino A.L.C. CPU Cooler
Very quiet, VERY cool, cheaper than many CPU fan coolers, much smaller than many of them too.
GPU: EVGA GeForce GTX 275 OC
Good without spending gobs of money. When it gets too dated in a few years, I'll buy a second and use SLI.
Memory: OCZ OCZ3P1333LV6GK DDR3 PC3-10666 1333 MHz 6GB Platinum XTC Triple Channel Kit (7-7-7-20)
Good, fast, cheap ... shiny.
HD: Western Digital VelociRaptor 300GB Hard Drive WD3000HLFS - 10K RPM, 16MB Cache, SATA 300MB/s
Fast enough all by itself w/o messing with RAID settings, etc.
Sound Card: Creative Labs SB0880 PCI Express Sound Blaster X-Fi Titanium Sound Card
Get this and not the Creative Labs SB0886 PCI Express Sound Blaster X-Fi Titanium Fatal1ty Professional Series Sound Card. It's the EXACT SAME card for ~$40 more.
Case: Cooler Master Cosmos S
Man, this is a beautiful, big, solid box with beau coup features.
Bling: Scythe Kaze Master KM01-BK - Fan speed controller with 4 system fans - black
Neat blue numbers ... what more can I say?
That's it ... well, lots of ties and wires and fans, etc.
