ATX Power Supply Bracket for Anet A8

I needed to enlarge the hole around the power input and switch to accommodate the power supply I had on hand (a Seasonic 550W modular power supply that I previously used on a Bitcoin miner).

If your power supply is as large as mine, you might also need to mount it to the frame with standoffs in between, as the other end of the power supply bumps up against the back of the frame.
