I did this build for a friend's birthday. The goal was to get a look as stealthy as possible from the front and make it look as much as possible like the original. The case itself is a repurposed Victrola classic turntable from which I removed all the internals.
Components were mounted using mainly velcro tape and industrial quantities of hot glue The motherboard is mounted on old noctua standoff I never used and kept on the side.
The back side is the only part that shows what's inside. The 2 exhaust fans were mounted on the outside since there were not enough room left in the case to make those fit. Front intake is taken case of by 2 80mm arctic fans located right behind the old speaker grills. Those have been tested against more traditional dust filters and offer the same level of performance.
The font panel is not entirely wired as my knowledge in electronics is really poor. The play button works though and is used to power on the PC.
Some photos show some RGB lightning coming from the inside of the case. Those are the RAM sticks and they have been disabled in iCUE.
