- The author built a DIY 10-inch mini rack using 20mm aluminum extrusions to tidy up six 1L PCs and external power bricks.
- Instead of 3D-printed or prebuilt metal shelves, custom-cut aluminum sheets were used, though alignment was tricky.
- Two 10-inch rack-mount PDUs had to be mounted vertically due to extrusion interference, and external power bricks caused clutter.
- Cooling involved USB-to-fan-header adapters, and networking included separate gigabit and 2.5Gbit switches for VM migrations.
- Total cost was about €313, excluding fans, with side panels in aluminum and top/bottom in wood, improving desk organization.
