If you have one of those, you know that they can get rather warm—almost hot, in fact—when the computer’s running full blast, and I thought it might be cool to have some kind of holder so that the transformer remains straight up, offering most of its surface to the ambient air.
Turns out it’s a rather simple hack. A piece a wood, rather thin, at least 3 inches long, 1 inch wide is all you need. The power supply itself is a hair more than 1″1/16 thick, and so you need to (band)saw a rectangular hole about 1″1/16 wide and 1″ deep, as shown in the diagram:
And it’s OK if the hole is just a microscopic amount narrower, because it will allow the power supply to fit snugly (and the wood isn’t infinitely rigid, it will stretch a bit) and the whole thing will be more stable. The final result:
