My computer rooms

There are two computer rooms.
This is the primary computer room.
It contains three tower machines running Windows, and one Apple Imac. The two machines You see underneath the table are sharing keyboard, mouse and screen.

This is the secondary room.
Here You dont see any computers, but instead three 3D printers. But in the room there is one tower, one all in one computer (HP), one small scale computer (Lenovo) and one Thinkpad all running Windows. Then there is a Apple Mac Mini and a Macbook Pro.

The towers in both rooms are home made.
