Dual PSU's, Linux
- Power consumption
Consolidation and mobility for ease of use. If you have any problem its easier to restart one machine and mobility because my power cost is rated for an initial 600KW of power at 0.04 and jumps to 0.14 after so my machine gets moved once a month every once in a while; yes, it's worth it.
I use less power than you would running two dedicated rigs. I only have to power one CPU, 1gb of RAM, one USB and one mobo.

Board is a MSI BigBang Marshal B3. It has 10 rear USB ports with room for a lot more. When I move to FPGA's this one rig will be the ultimate hashing beast.
