My desk setup is so crap it makes my arms hurt haha. When I get the keyboards I'm waiting for in the mail I can finally remove all the keycaps from my other desk and move the computer there.
I already had that enclosure, so I decided to use it instead of ordering new ones. I already bought one which was too small for the ps2 plug. Regarding the I/O placement, I originally planned to expose the Teensy's usb port directly by mounting it near the wall with velcro, however, it wasn't stable enough (I couldn't even insert the cable without holding it with my hands) so I had to use the usb panel mount instead. Since I already had a hole I had to put it there. Now why usb and ps2 are on the same side is because the enclosure is so big, I thought it would be possible to use it for multiple projects!
