Most of my machines are complete abominations. Having untidy wires or one little DIY bracket is preschool level hackery. Back at the end of 2003 I slapped a P3 550MHZ board into a Budweiser box. Had it hooked up to a receiver playing music 24/7 for several months. Eventually I moved it to a proper case. Ran the heck out of that machine for years and it was the fastest booting machine I ever had until I got my first SSD. I also had the cardboard washers for the power supply and CD drive.
Amazingly, I still have the box! I used my phone's camera for the third time!
