My brother recently gave me two desktops. Problem is no updated drivers since Windows VISTA in one and the other machine is an unknown. Trying to decided:

Find a VISTA install disc
Install Linux and hope for drivers (I do talk Linux.)
Gut the machines for their hard drives and memory

Obviously no chance of Windows 10 working.

And who knows about the unknown machine. No markings at all.

Probably great machines in their prime but not really worth much now.
