Wow, who would’ve thought you could make a Lego PC?
Most things worked out amazingly well, like the ATX power switches fitting perfectly snug in the space of a 1×1 brick, and the LEDs fitting perfectly in a 1×1 brick with hole. I hot glued a 1×1 brick to the power and reset switches to act as buttons. I also put a dab of hot glue on each corner of the ATX I/O plate, which was just a little too small to fit snugly.
I also realized that I underestimated the cohesive strength of Lego bricks. When I first put the top on, I couldn’t get it off! I had to add a nearly complete border of flat plates from my spare parts to get it to detach easily.
