Q: These are the technical specifications for this system. http://support.dell.com/support/edocs/systems/dim2300/specs.htm#1106201 If so, what are some compatible motherboards?
A: if you know how to build a comp yourself or are comfortable doing it. you can upgrade pretty much any modern day PC by making sure that the new motherboard has the same socket type for your cpu and supports the same type of RAM. beyond that you should be pretty much ok. but in general it is better to just sell and by something new. dell doesn't make good computers to begin with
