This is what I got from the vice president. (seems like they care alot about their feedback.)
The power supply that normally goes in cases of this type is not anything special, but it is sized to accommodate the power needs of a power hungry system that buyers usually put in this case.
We don't want you to be "stuck" with a case you can't use. We do sell power supplies on our other site, if you want to shop for one there, we can give you a discounted price. Here's a link to the store:
eBay Store - DealMonger Clearance Store: Tape, CD DVD Players, AutoMeter Gauges
I that doesn't work for you, send the case back in it's original packaging and we will give you a full refund.
Please let us know what you want to do.
(weird thing is that, I have used same sized power supplys on both full and mid towers.)
