It's kind of unfortunate that eurorack cases and power supplies tend to be so expensive. My approach is to use cheap Meanwell supplies (a pair of RS-35-12s wired in bipolar configuration rather than the more common RT-65b) and laser cut more racks out of birch ply when I need more space, but if I was paying full retail price for rack space I would probably be using much smaller modules, and fewer of them. (This is my most recent design: http://jsnow.bootlegether.net/84hp-rack-2row-slantback.svg http://jsnow.bootlegether.net/84hp-rack-2row-slantback.svg -- the parts are made by running two jobs on the same file, always cutting red and alternating between cutting purple and blue. Turns out 3mm screws work fine in plywood if you can get the hole size just right.)
