HP EliteDesk 800 G3 Mini, i7 7700t, 256GB M.2

a 1 liter PC with an intel i7 7700t (7th Gen)
This is a power-house of a tiny PC.

These units have 3 Full Size DisplayPorts on onboard.

Once you go two monitors, you never go back to one. Don’t get me started on THREE monitors
Just imagine how productive you’ll be with three large monitors.

I almost forgot, the 7th Gen i7 will make light work of nearly any workload.
