Acer Aspire Revo mini PC (2009) (Kingsholm GL1)
Old mini PC, from 2009. It is very unlikely you will get any modern OS running well on this, but it will (grudgingly) run Windows 7, a clean install of which is installed now. Comes with the power supply, but you'll need to find a keyboard, mouse, screen etc. The BIOS battery inside is also completely toast, but after setting the date it runs fine.
