Bench PSU Housing

Hey, So I didn't give up, but I built a few board up and decided I needed a bench power supply. I have been designing a bench supply for a while now. I have started putting the case together. I have cut up the front of an old draw and am going to make it into a box to house the design. Last night I marked up the wood with the components I want on it.

 Then I have drilled and sanded for my life until the holes are the right side for the components. Here is the back, and below is the inside of the back. I have made a little bit of a hash of the front so it needs more work. I have the circuit for the supply nearly complete, but i'm still grappling with a few calculations (although im sure it'll all change when I get the design out of the simulator anyway!) - I have purchased a transformer which very shortly I will put a dynamic load that I have at work over it and figure out exactly how many bolts and amps I am going to get out of it. I intent to try and make a printed circuit board, etch it myself (because I can't sure veroboard for this project, as I'd smoke the copper track due to the high current). I'd like to finalise the circuit in the simulator before I get to the task of laying out a single sided PCB (as I beleive double sided will be too tricky). Watch this space for final schematics. Hopefully I will finish it soon so I can get on with the task in hand, which is building the synth! (Project update: I have the first two boards completely built up, thats Midi to CV, and Waveform generator. I just want a current limiter to test them with to ensure I don't smoke any of my lovely components!)
