Someone mention VIA mini-ITXes?
If I could have the resources, I wouldn't fan out a single PSU
to several mini-ITX boards. It would be cheap, but introduce a single
point of failure, and you'd have to cobble somthing together to
deal with ATX power on/off.
Funds permitting, one of the small 12V DC-DC PSU per board.
Then run a high current 12V supply along the rack.
Simple cheap relay would do the job of power cycling also.
On the VIA front, the smaller nano-ITX form factor boards are due soon.
Could make nice building blocks.
