It supports standard UEFI boot, Ubuntu has a WIP image you can use that has some extra patches, and with some fiddling you can get other distros, assuming you use a really recent kernel with a supported device tree and maybe you need some firmware updates and a kernel patch or two (search 'x1e' in the Linux tree to see if yours is in there.) Wifi, USB-C etc work last I checked. Not sure about BT or general sound support or anything like that. Overall though, things "work" but as far as usable goes, it seems to remain in a pretty poor state; especially given the lack of accelerated graphics combined with no NUC/SFF options. I guess WSL2 is probably okay. But it's a shame, because the hardware does seem pretty nice. When some NUC options come out you'll at least be able to use it in a headless form factor, I guess.
