The socket size is LGA775. The specific model of the current MOBO is actually a ECS P4M800PRO-M. i am looking with a MOBO that has everything this one has, plus some more fan ports and better drive connector placement, with the FDD on the side near the drive bays/cages.
however...
i was thinking of turning it into maybe an PC that is for show: kind of like to remind me of how far my PC's have come along since i started building PCs way back when, like the time line section of the dinosaur bone collection - just something to reflect on, really. it would be nice to get it in a working condition, just in case i want to go back to play DOS games. i thought of this because i don't really have anything from this PC to transfer over. otherwise, i would use it for spare parts.
if i decide i keep it as a showpiece, i shouldn't really spend any money right, to keep it vintage in the years to come?
at the moment i am just tearing apart the PC to clean the parts, and assessing condition of parts. i thought about a small form factor case to house the old parts in, but maybe i should just clean it up first.
would the Antec Skeleton (mATX form factor version) be a decent case for a showpiece? it would defeat the purpose of keeping it old school

. i do have my old dynex case, but wouldn't it make more noise because the sound would just bounce around in it? the PSU in this case is an ANTEC 400W SL400
