@subroutine @manawyrm Honestly, I'm pretty sure with the OneCoreAPI and all updates from LegacyUpdate installed, you could daily an XP install!
This system is, driver-wise, fully supported, since 4th Gen Intel Core i/Xeon E3 v2 platforms still had drivers for the chipset available! Granted, it's not *modern* modern, but still pleeenty fast and usable. I do want to try a PAE patch to allow more RAM to be usable even on 32bit Windows, but I've heard it can be quite unstable. Hmm...
