I have two ECS D6VAA Dual PIII Mainboards, and am in the market for a third. I paid about $50 ea. over a year ago, and saw them on eBay last night for $25 and $35! Take one thing into concideration though, only the PIII chips work dualy, not any of the socket 370(FC-PGA) Celerons or CyrixIIIs work that way. Also be sure you have a genuine FC-PGA socket 370 chip, as the socket 370 FC-PGA2 chips do'nt work, without adapting, that I hav'nt tried to terminate with. Termination is when you only have one chip in one socket and then fill the other socket with "Terminator", wich is a chip that just balances electric currents, so neither socket burns out alone, but has no other function at all. Terminators cost about $5. Another catch is it's RAID system, they say they come with RAID and Four IDEs, but this is'nt true for all of the D6VAAs, and not either of mine. You may also be looking for SCSI and/or ethernet cards for 2 of the 5 PCI slots, but other than that it's got most everything!
