looks like quite a decent start to me...
personally I'd want some more utilities... as they add more patching options... so versatility
& some modulation - envelope generators/function generators & lfos
and I'd probably go for a bigger case (mantis would be my choice - bigger/quieter/cheaper per hp etc) - sooner or later you'll inevitably need it & you're a bit close to the power specs for the uZeus - at least with the regular psu - & with the higher powered option there's no improvement on the -12v rail - remember to leave at least 20% headroom on all rails (& if you add more modules you'll probably want to change the jumper for the -12v to get the extra 100mA out of it...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
