what kind of specs can we build a mini itx these days? I haven't looked into it, but the small form factor is a pretty big premium. I'm not sure I could build a ~ Raydon 7600xt micro itx build for less than $1K usd? (I haven't really looked, though).
For me, I'm looking at this like a nice micro itx build, and I'd probably pay up to a grand for it. (pending final specs and performance reviews, because it's kind of hard to compare it's custom chips on paper.)
I haven't checked in detail, but I would suppose SteamOS isn't far off from running on general-purpose PCs. Else, I've heard a lot of good things about Bazzite.
Why do you have to install Windows? You could put bazzite or any other distro of your choosing on this machine and have a similar experience to the official Steam Machine.
