It really isn't very difficult to fit an amp and power supply into an ATX case. I've done it a few times, and though it is a bit tight, the amp fits nicely. Be sure to use a fan, though, because things will get a bit toasty without any airflow.

i should point out that it wasn't my mod

fitting it in isn't an issue at all, but running it from the supply itself can be

ah yes, the exploding caps - but to be fair that one cap was an oversight. wasn't needed anyway

amp works very nicely

heatsink is VERY undersized but PSU is fan cooled anyway so it really doesn't matter, that said it does get mighty toasty. but it ain't broke and so it ain't gonna be fixed

Since few months I'm using 3 old computer power supply to feed a 12V amplifier (rated 225W). I use the 12V outputs in parallel to get around 30amps at 12V (amp can pull 40amps max).
I use diodes on each output.
When I use the amplifier near to it's limit, PS voltage is dropping to 9V, it's not a stable 12V. Also diodes drop voltage a bit.
I think it is the cheapest way to get 30amps at 12V and until now it is reliable.
36V in serial can be done too.
