Thanks for the great help everyone. I was almost giving up on this whole idea after reading about DIY cases that cost between 400-500 euro's... And then the 'custom' ones ranging from 1-1.5k .... That's nowhere near my budget. I'm thinking of postponing my ideas to the summer when I'll have some more time to build it myself, but the synth racks looked quite affordable. Perhaps I'll start with one of those.

If anyone has other alternatives or ideas (or selling a 2nd hand case w/ power supply lol) I'm still all ears as I'm trying to navigate myself a little bit before spending hundreds of euro's :)

Cheers,
