> Does anyone know of a source for an appropriate power supply, or a kit, or even just plans for one?

I'm working on a PC-based MP3 player for my car, so I've done a fair amount of looking. There are a couple of sets of plans floating around the net, but the current they generate is inadequate for my purposes. This is a good resource, with links to many examples of DIY projects.

The only commercially-produced DC power supplies I've found are made by Arise. They have several models that might suit the purpose, like these.

If anyone is aware of a better solution, I'd love to hear about it!

I developed my own mp3 player as well >:P
Arise Computer. They're nicely made to fit into the same space as a standard supply (they also have mini versions, if you're making your own box), and cost under $90. Considering that most homebrew dc-dc supplies cost about $50 in parts alone, there's really no point in building your own.

By the way, as of right now, Arise only sells AT supplies. However, I've called them and inquired about an ATX (+3.3V) supply. They will have one out in "early November" for $90. Well worth it.

These are the systems Maximum Linux used.

Found a site, Arise Computer Inc, who have a whole page full of ATX power supplies that should suit your needs. Looks like they've got 5 on this page which will take DC input - just select one that's got the input voltage you need and away you go!

This isn't solving the problem of housing all the boards in one case all on the same backplane. Using a rack full of boxes isn't always the best solution. Although putting them all on the same backplane isn't much different. Sometimes you just don't need everything that comes with a complete rackmount system. There are products available that take .5u per system, 32 systems in 16u

I'm curious about this kind of configuration also. Althogh I just want to pack as many cpu's in as small of space as possible and have them all on a fast switched backplane for comunication.

SBS-BIT3 has some solutions. They have a 20 slot ISA passive backplane that has 4 segments.
