Installed a vent into the desk with a high powered fan underneath.
Figured we joked about it enough, but this thing keeps my office snug & warm throughout winter without having to expend a single extra cent in heating.
Nice! I would've done it high on a side/back wall, just to not interfere with desktop space.
In fact, I put a compressor fan in the top back of a desk cabinet for the same reason, and wired it to a USB plug so it ran from the power on the back of the PC.
