You'll need another OptiPlex board -- you may be able to use a slightly newer one but nothing standard is going to fit that case. If you want to use a standard board, plan on replacing the case, power supply and heatsink assembly.

The truth is any optiplex 7xx series (745,755,760,780) motherbaord fits in this case as they all use identical btx motherbaords the best motherbard that could go inside this case is the motherbaord for an optiplex 780 these are $15 to $30 on ebay they have ddr3 memory support and can run core 2 quad cpu's you may also want to get the right form factor as these boards do vary by from factor (sff, desktop, mini-tower).
