@burnin,
If any chance please include various extension/conversion cables on your website for those who already have PSU.
I switched to Cooler Master V1000 PSU and probably will be needing some of the variants listed below.

SATA to PCI-E 6P (need three of these)

MOLEX 4-pin to PCI-E 6P (now I have these but someone else might need them)

PCI-E 6P extension cable (probably need 8 of these since I am not sure what will be final distance between two bitburner xx)

Please excuse my ignorance but I am still unsure about other type of connectors we will be able to use beside PCI-E 6P when using PSU
