I would advise against doing this. I wouldn't know where to get an Y connector like that.
ok, that's good to know.
Now I need to find four cheap, compact power supplies :-)
no disk in this system, no cdrom, no nothing save for motherboards. I'm looking for small, cheap, good supplies. Probably don't exist but anybody know for sure?
Maybe try one of those 1U power supplies. Similar to the one I had with me during USENIX Something like:

and the power supply in action:

It should be fairly easy to stack 4 of them side by side and tie together.
