Yeah, you read that right! I had no spare case for a test "retro gaming emulation type pc", but had a few shoeboxes left around the house. I took the biggest I had, and just thought "why not, """""lmao"""""".
Step 1: Things You'll Need
-A box, preferably a big one (Nike/Adidas/Timberland/Crocs)
-Screws (for the fan, so find what suits them)
-A fan (not a JB one, please)
Step 2: Cutting Vents
First, you'll need to make holes in the cardboard for air to flow. Cut a 100mm hole for the fan, and some more "screwdriver holes" to get some fresh air to the CPU.
Step 3: Making Standoffs
Cut some cardboard and glue it to where screw holes are on your motherboard to support it.
Step 4: Install Your Motherboard
Step 5: Make a Foam Base for Your Hard Drive
All is in the title ^^
Step 6: Connect Your Cables
Step 7: Don't Be Dumb (like Me)
Yeah, so, I didn't calculate the fact that the box could not be closed because of the fan touching the GPU... So I mounted it on the other side.
Step 8: Connect Your PSU
I did not have a small enough PSU to put in the case, but anyway, connect it and fit it if you can (make some holes for its fan too)
Step 9: Biem, You've Got M̶a̶i̶l̶ a PC
Here you go! Fun little project that you'll maybe have fun making ^^
