I don't think you can get a replacement motherboard from Dell to replace the one you fried. I don't think they sell those seperately. At least they don't for their Laptops. The only way is to send it in for repair...which might be tricky/expensive considering you obviously messed it up

Definately check compatability, and get that computer working though!



BTW, I think Dell makes okay computers, though I've never owned one except for a used PowerEdge 4300 Server. But their support isn't that great (relayed expirence someone had trying to get a compatible PSU from them), but looking at other manufactuers, nobody has good support now a days I think.
