What did you do for power supply? I have been looking for one for my 3000t for about a year now.
The original one, which came with the case, is not working (power good- signal stays low).
I have built my own adapter to use a modern ATX PSU, I bought an ATX motherboard expansion cable, changed the pinout on the 3000T's end to match it and added a small board (parts needed to generate the -5V that's missing from modern PSUs).
It's not pretty and it seems to be a problem to get an ATX PSU that would provide even close the 30A on +5V rail that the original PSU does. So far my Corsair MX430 has worked fine (under load the +5V rail drops to about 4,93V).
