Micro-ATX will fit, but might be a tight squeeze with ATX.

check pic to give you an idea.

Awesome..thanks a mill

Be awere that the Dell "case plugs" may not plug directly into another motherboard.  

I mean things like the power on switch, HDD LED, case speaker, and USB plugs.

I wanted to put my Dell Dimension 2350 setup into another case for better cooling (cheaper than all the fans, parts, and tools to do a case mod). I found that the new case plugs (Antec 300) could not plug into the old Dell motherboard. And I wasn't about to try to "re-wire" it and botch the whole thing!

Seems that Dell "modified" their motherboard connectors to work with their cases.

I wish I had pictures for you, but one thing I can tell you is that (my) Dell case had all these "wires" for their case compontents into one connector, that was incompatable with the case I wanted to put it intos wiring. I even looked at my other case(s). No Deal!

You have beed warned!  

BTW: What is your systems processor base? Pentium 4, D, Dual Core, etc?
Nevermind, I just saw it's a upper-end P4 system >2.4GHz. What socket? 775?

Good luck finding a P4 board with PCI-e....but I guess they are out there!  

Doogie, I have an 8300 and thinking of doing the same for a HTPC build on the cheap. Did you manage to upgrade? Would be interested in your story.. issues, gothcha, before i spend any $$$.
