The uZeus supplies 2000mA on the 12V rail and 500mA on the -12V rail, and your system pulls 1735mA on the 12V rail and 466mA on the -12V rail.

It's technically "within specification", but you're really pushing it. You want to be under 80% of the rating of the power supply because sometimes modules may pull more power than is actually specified (especially when turning the system on). You'll either have to sacrifice a module or get an additional power supply that doesn't take up space in the rack.

I'll leave critique on your module selection to somebody that's into ambient/drone type stuff.
