I build my own computers, I use Asus MB's and Intel Pentium 9xxd's and eVga 7900 GTX 512's, I get lost from the world in this little corner of the sun room.
Thats just a desktop with the asus ai booster. I can monitor cpu temps, voltages, fan rpms fsb etc. If my frame rates slow down on me I can overclock her a bit. Usualy I have gps and other windows there, but I didn't for these pics.
