My computer: (updated: 1/19/2013)

Antec 900 Case
i7 920 2.66GHz clocked @ 3.2GHz
Cooler Master V8 CPU Heatsink (Original fan died after 4 years, replaced it with a XAF-F1255)
Asus P6T Mother Board
12 GB (3 x 4 GB) G.Skill Ripjaws DDR3 1600MHz memory @ 1600MHz
500 GB Western Digital Caviar Black
Corsair 750 Watt Power Supply
GIGABYTE Radeon HD 7850 1GB

Recently tested with the newly installed memory and fan replacement, LinX for 30minutes proved it was stable and never crossed beyond 80°C. My computer never reaches 100% cpu or memory usage so the temp is not a big concern.
