Help with HP AMD Opteron Mining Cluster

[nusi]

Hi guys, a bit offtopic, though...
I want to build up monero mining on old Opteron 6220 and Opteron 6238, and bought few along with motherboards HP proliant DL585 Genuine HP DL585 G7 Server Board 5x PCI-e Expansion Slots 604046-001 w/ Warranty | eBay

But, the question is how to attach HP common slot to my motherboard? or is it possible to attach regular non-server power supply?

Monero mining almost not profitable especially on power hungry CPUs.
Use HP power backplane to connect PSU with HP MoBo

Yeah, thanks, I have already made a 8-HP DL385 G7 (instead of HP Dl585 G7) - in my country I have 6.2 cents per KW, so it's still maybe profitable or may not (because I have lost 3 motherboards - actually my fault , wrong operation).
But due to Monero recently decrease the reward for block finding - it's not so profitable as before.
