P4 Mobo

[qwazzy]

My mom has a P4(3 GHz). It's in a Dell. What form factor are they. Micro ATX, BTX? Help. Also make suggestion on a good mobo less than $100 for the comp.

They're Dell. Dell uses proprietary boards. Regular atx and micro atx boards won't fit in many Dell systems. List your model number or try ebay. Otherwise, I would buy a different case and transfer everything over with the new motherboard.
