Remarks
Everything works, has PS/2.
Beware, thought it has 3 USB controllers, all USB sockets are wired to the same controller (the other two are not used at all (You could wire it up, because it has sockets on the motherboard)
I think it was not possible to install in UEFI mode (but BIOS version is quite old, I have noticed now). BIOS install went fine.
