Here's my 4x5830 rig. Two cards are running directly on the mobo, two are running on PCIe adapter cables in the second tier. Yes, the skeletal chassis as such is an old table that was taken apart and put back together. I've since moved this setup from my dining room table to a small desk in the basement and it has a box fan on one side blowing through the videocards (the temps are
quite low). Each card is putting out 310 MHash/s for 1240 MHash/s total. Oh, and the OS is Linuxcoin running on a USB flash drive.
