I finally found the time to complete my 12U 84HP eurorack modular case.
In the end I settled on two separate switching Meanwell PSUs, these are very cost effective (below 30USD), they have both +/- 12 V and a dedicated 5V rail (useful for digital modules like my PEG), the power supply is very clean and I see no drawback whatsoever compared to the linear PSU I was using before (I did my own PSU with a tore transformer, similar to the standard Doepfer PSU). For the power distribution bus boards, I used el-cheapo stripboard with shrouded headers.
The eurorack rails are fitted with M3 threaded strips, much more convenient than sliding nuts, I got them from Schneidersladen. The handle, rubber feets and latches are made by Adam Hall and I got them from Thomann. Enough talk, pics!!
