I would bet you can find several opteron boards that have this slot. 
Some of those are probably single opteron, but capable of using dual 
core (I believe socket 939).

Not sure what the state of SATA is right now, but I'd bet that for 
single drives they have some good ones. If you wanted cutting edge 
though, you'd need 15k rpm U320...especially if you plan to run more 
than at once. Looks like *some* of the SATA drives now support the 
native command queueing in the way that all SCSI do.
