Is there a place that i can buy a HP socket 370 motherboard, and if so where? I know HP's have proprietary motherboards so there is no point in trying to replace it with a different brand.

ok, since nobody seems to know, is the only reason the hp mobo proprietary because it doesnt fit the case? Could i just buy a different brand mobo same socket and just kinda hang it out the case? it might be "ghetto" but its ok, i just need to know if a different brand mobo will work with all the HP components i.e. psu, ram, processor, pci cards etc.

If I were you, I'd just yank all of the usable parts out of the HP, buy a new case and mobo, and install it all in the new case. Cases are cheap, (you can get one for $30 with PSU if you're not choosy) and all of your old HP parts (with the exception of the heatsink on the processor) should work on a new motherboard.
