The Intel ISP1100 would fill the bill. Fits in 1U (though it's a
DEEP 1U). You can find them on eBay or at Weird Stuff if you're
in the Bay Area (which, as I recall, you are). Try to get one
with at least a 700 MHz Pentium III. Works well with ECC DIMMs.

Only catch is that one of the cards must be a "mini" PCI card. (The
interface to the card is the same as PCI, but the bracket is shorter.) 

The BX chipset only supports UDMA-33, so you'll want to install
a fast EIDE or SCSI card.

I built one up recently.... Put a Promise Ultra100 into the full-sized
slot (with Granite Digital Teflon cables -- they're the best!) and 
an Intel EtherExpress 100 card into the mini slot. I could have bought 
a short bracket for the NIC, but since they're hard to get
(the form factor never caught on as a standard) I just used pliers
and a nibbling tool to bend and cut the bracket that was already 
attached. System has worked perfectly 24x7 ever since.
