This is my main computer, I built it this time last year:
Case: Cooler Master Cosmos S
Power Supply: Antec NeoPower 650
Motherboard: Asus P6T Deluxe
CPU: Intel Core i7 920 (C0 Stepping)
RAM: 3GB Corsair DDR3 1333MHz (tr3x3g1333c9)
Graphics: NVIDIA GeForce 8800GTX, temporarily only one, normally x2 in SLi, explanation below
Hard Drives: 1x 60GB OCZ Vertex (running firmware 1.40 (TRIM)), 1x 500GB Seagate 702.11 (running fixed firmware)
Other Drives: ASUS 20x SATA DVD Burner
Over past few months the fan on my Intel Core i7 stock CPU cooler started failing, the fan initially halved in fan speed, then slowly lost ~50rpm per week while my CPU temp crept up, fan control was off and there was nothing blocking the fan from physically moving, so I decided to replace it.
