I bought a Gigabyte 8i875 ultra and three 8i865pe775-g-rh Rev4.9 motherboards, they were pretty cheap since advertised as not working.
I will find out what's wrong with them once they arrive.
the socket 775 boards support C2D E7600 and C2Q Q6700 with modded bios, really decent agp boards.
For the three 8i865pe775 board, at least one problem is obvious: bad/bulging capacitors. Let's hope that's all that's wrong with them, as that would make them an easy fix. Otherwise, I tend to be weary of stuff with LGA sockets, since they often get mistreated and get bent pins.

To keep the thread on topic, I have just acquired these three boards which potentially aren't retro enough but still -
This one above the seller didn't know what CPU was present but having taken the miniscule heatsink off... is a QX9650 so this should be a nice one to play with! If it had that cooler all its life it must have sat at thermal throttle all day long? 😀
Ouch!
I hate those slim stock Intel coolers. Aside from being barely adequate even for the Core 2 Duo chips, the push pin retention is surely to warp the board and possibly break the CPU socket BGA over time. So I hate these coolers with a strong passion. And yea, it probably sat at a very high temperature all it's life, even in idle mode. I don't want to try to imagine how hot it got with a large CPU load. Probably at thermal throttling or thereabouts, as you say.
Fairly recently, I picked up a similar era PC for my nephew. It had a Q8300 in it with a slim cooler like this. The thermal paste on one of the two cores inside seems to have degraded (probably from running hot all the time with that small cooler), because I consistently get high temperatures on one of the 4 cores, even with a much bigger cooler. The PC also had a decent GPU in it too. But going off of what was on the two original HDDs, there weren't any games on them. And from the lack of dust, I don't think the PC was pushed hard. So that probably helped a bit. Still, the CPU BGA on the motherboard is starting to go bad from the stock cooler, as some of the memory slots don't always recognize the RAM if the board is flexed or even touched a little more. Definitely running on its last run, but seems to have stabilized for now, so I gave my nephew this PC and he's been happy with it so far.
But hey, it was $2.50 for the entire PC combo: an ASUS high-end mobo, Q8300, 8 GB of DDR3, GTX 560 Ti 1GB, x HDDs (1x 500 GB and 1x 200 GB), a "500W" PSU (no name, but built OK enough for 250-300 Watts), and the case with a DVD drive. Not a bad deal at all, IMO.

which would you guys go for out of these two?
Whichever doesn't have an nVidia chipset. 🤣 🤣
Well, both are Intel X38 chipset, so I suppose both are pretty good boards.
I don't usually have any brand loyalties, but I tend to prefer Gigabyte boards... or at least it always seems I've had poor luck with ASUS boards and something not working (or the entire board not working / dying.)
Is that a water block on the NB on the Maximus Extreme? If yes, perhaps it would make more sense to go all the way and add a water cooling for the CPU too? Seems odd to me to have WC on the NB and nothing else in the system.

This poor, poor CPU is a victim of compound abuse. I'll begin cleaning this soon but it's a bit of a mess.
Also, beware of those brown electrolytic capacitors near the CPU - they look like Chemicon KZG series, which on old board like this tend to be problematic more often than not. At least these appear to be the 2200 uF (6.3V) ones and not the larger 3300 uF cousins, which have a very high failure rate.
The green KZE series can stay - these are the complete opposite of KZG in terms of reliability. They won't ever cause issues.
