I have an ingenious little table next to my bed which I made. It is the most intelligent thing I have ever seen. It is kitchen shelves for holding food with a piece of wood on top as a bench. I have repurposed it to be a desk next to my table so I can keep shit on it. Why spend money on a proper bedside table when I can ingeniously combine random parts to make my own, autistic, innovative furniture?
This was like ten years ago, but...
The fan on my video card broke, I took off the side of my computer case and put a box fan there. Kept the card nice and cool.
