I started with these cases but ..if you have to buy a power supply new I wouldn’t recommend the investment at that point you’re better off getting a 3U rackbrute which gives you 83hp instead of 60-56hp. They’re too small but as with anything you could probably do fit smaller digital clone modules and such and make a complete system. I had a leftover case and I’m currently using it to expand a m32/dfam rig. Would really look in nearness for a compact stereo mix solution.
