Re: Motherboard Help
I couldn't really find any info based on that model number, other than the board is very old and supports socket-7 CPUs. Are you trying to replace it because it's gone bad? Or are you trying to upgrade the PC? It seems like you might be better off just upgrading to a new machine altogether.
In any case, as others have said, motherboards use standardized form factors (ATX, Micro ATX, ITX, etc.) If you buy a replacement board with the same form factor, it should fit in the case.
If you are keeping existing components such as CPU, RAM, etc, ensure that the replacement board is compatible with them also. (Same CPU socket, same ram type, etc.)
