Couple of thoughts. In a system this small, six VCAs feels like overkill... I'd cut the Tallin. The VU meter isn't necessary, nor is the mult (use stackables if you're running this small). That saves you 10 hp.

From there... I notice that you say you want random/glitch. Nothing here really does that. You could throw in a Nano-Rand for 4hp. That leaves you 6hp for something else, and one thing missing here is effects of any kind... perhaps you're looking at using out-of-rack solutions for that, but something like a FXAid would be great in here.

But still, the best advice would be to get a bigger case, if you can, even if it's just an Intelligel 104hp Palette case. This is going to be pretty limited.
