I’ve been keeping an eye out for the BD790i X3D since they confirmed they’d be releasing it in March. Looks like it’s available in the EU but I haven’t found it listed on the minisforum.com website yet
Edit: looks like they added it to the US site: https://store.minisforum.com/products/minisforum-bd795ise?variant=46451384385781
As opposed to a regular itx board?
It looks like this may have decent cooling with an exhaust out of the rear io panel which is uncommon to non-existent on itx boards. Might make for an ultra compact machine with less stress on other components since the heat is ejected out the back instead of circulating around the case.
I’ve basically sworn-off of Mobile PC hardware for desktops after I got a Mac mini and nuc ~15 years ago.
