Sweet rig. Where did you get the aluminum extrusions? Is it 80/20?

Ok, time for a bit of showing off my rig:

5x Sapphire Radeon 7970
3750kHash/sec Litecoin
and blowing the heat right out of the window!

Maybe instead of blowing out of the window, you could turn down that heater hidden behind the desk and reverse the rig to blow inside ? Cheesy

Nice one !
