It looks like it's meeting your needs.  It's *really* hard to tell from the pictures what to think.

Only way to know for sure would be to scope your PS under different scenarios and using a programmable load.

If you have a scope, try hooking up your supply across a switch and a power resistor and probe the output of the PS while turning the switch on and off.

Repeat the same test, but switching the PS on and off, both with switch open and closed.

Other tests might destroy your supply, so I don't recommend.  If you have a DC current probe, you can also look at the current signal.

I built this one a few days ago.  It's a pretty normal 317/337 based dual rail based on a few schematics I found online.

Sorry but I'm always against wood an cheap plastic on home made power electronics. This thing is a fire hazard.

Nothing wrong with plastic. The HP/Agilent E361X series are almost totally encased in plastic. Thick plywood is even harder to set on fire than plastic.

This looks like a neat little el cheapo unit :) I'm getting one myself just to have a look at. I may run some tests when I get it and post results here.
