I think the biggest concern on mine (and I would assume others like me but I cannot be sure) is that I cannot make the correct modifications to power supplies to power these things.  Could you possible consider an option of adding premade wires or something that all I have to do is then connect them to a standard ATX power supply?  That would be helpful and I know that you would get at least a couple of orders from me, and a lot from a guy I know looking to buy a couple TH's of machines but is concerned about setup.
