My PC gets very dusty after short time.

In my opinion it's because it sits on the floor so I've made a little table for it.

Tabletop is made of 6mm plywood.

You'll need 4 legs (obviously), 1 logo, 1 LED mount, 8 MSi dragons (printed in red)

I've used about 10cm red LED strip, powered with 12V directly from motherboard of my PC.

Each printed part is mounted with M5 bolts and nuts. At least 10mm long but a little longer will be better, like 15mm.
You'll need 12 bolts and 12 nuts for this table.

Tabletop can be scaled to fit your PC footprint.
Mine is around 20 by 50cm.

Plywood was spray painted black for better looks :)
