I'm also interested in mating an ATX supply with a QBUS backplane. I have a naked backplane (I think it's either Q18-CD or Q22-CD) that I bought off eBay, and I plan to (eventually) use it as a dedicated bench test backplane for working on boards. I figured I'd mate it up with an ATX supply. -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/
