hey im not to sure about this but what if he used this
http://www.newegg.com/Product/Product.aspx?Item=N82E16817101025
since the 8800 needs 2 power connectors one could connect from this (and then connect to his hard drive and cd drive) and his other psu could take the other load from the 8800 and the motherboard cpu
i think it would work quiet nicely.....
since he has such a small case
this this pops right in a drive bay
another solution would be to run dual psu
just leave one outside the case....
