Is the Pentium a socket 4?
Full tower has P-II and P-III stickers, it was upgraded. My guess is 500MHz.

Looks to be socket 7, but with a Pentium Overdrive in it? Not heard of that. I thought Pentium overdrives were for upgrading 486s. Could that be an MMX CPU in a socket that doesn't have dual voltage support?

Well, Pentium Overdrive came in different flavours. All had the purpose of making an upgrade "plug and play" and not having the user to set any jumpers or anything (except maybe for the 486->Pentium version).
It looks like here the laser etched marking in the top left cornor of the image says "200" so it's probably a PODPMT66X200 which is an MMX 200 MHz, with its own on-board regulator, making it highly plausible that it was use because of the board's inability to supply dual voltages.

I did, however believe that socket 7 was always dual voltage? Or was the only difference from socket 5 the extra available multipliers? Anyways, it isn't all unheard of that the physical socket is a socket 7 even the board is only socket 5 specs - it's been a question of avaliability probably.

You are correct! At least on it being 200Mhz. Not sure if MMX yet, but I would hope it is. Good news the PC starts and the IBM monitor seems good too. Quite a nice, sharp stable image on it.

Bad news is that although the 1.2Gb HDD is detected it won't boot. Just sits there with flashing cursor.

I have a motherboard that is socket 7 and supports only the original Pentium. But there is some kind of socket next to it for changing the VRM. I think putting an appropriate module would allow it to support MMX.

Not "found a PC in a dumpster" but "found in a dumpster PC": a few months ago, I bought a 2013 era super high end watercooled monster PC. Dual 980's, Rampage Extreme IV motherboard, the lot. But the PC was in serious disarray, non functional, leaky watercooling, dead motherboard..., partially disassembled but everything still inside its humongous Corsair 900D case (which is about 4 PC's large, for those not in the know). But I bought it for very little money, basically bought the case and got the rest. While going through the trainwreck inside the case, I found on the bottom not one but two Samsung 512GB SSD's, never installed. In the current economy, that is quite a find: that pair of SSD's would set me back over 300 euros which is about 5 times what I paid for the lot. The PC itself had a 1TB HDD and 128GB Samsung SSD. I think the previous owner wanted to upgrade to the two 512GB SSD's but then noticed the motherboard was dead and kept everything inside waiting for a better day.

I have since traded the wrecked Corsair PC for a working more modern gaming PC, and use one of these SSD's in there without any issue. The other SSD is waiting for another PC.

Wow, that's one of the occasions making "risking a wreck" worth one's time. Kudos!
