Prototyping station!

I've almost finished putting this together, and I'm super stoked with it, had to share
It's put together from all sorts of old junk, but it gives me three 830-hole breadboards, and with two 19V 3.4A laptop power supplies into an LM317/LM337 regulated power supply I found on eBay it supplies +/- voltage that covers all the common stompbox and synth power needs (+/- 1.25 - 17.5V).
Some of this junk I've had laying around for 5 years, but now I feel completely justified carting it round moving between three different cities 

It uses:

• a fibreboard shelf I found on the verge for hard waste collection
• handles from kitchen drawers, left over from a kitchen renovation at work
• an oven tray that was used for a resin craft project and no longer suitable for cooking
• two old laptop power supplies that I'd hung onto just in case they were useful
• aluminium chassis panels scavenged from a solid state hi-fi amplifier
• a variable voltage power supply kit from eBay, with the two 5K linear trimpots replaced with a dual gang 10K log, modified to 5K linear by strapping 12K resistors across lugs 1 and 3
• the power supply PCB is mounted to the chassis using some right-angle standoffs and screws robbed from some other electronics junk AND the best bit is that the hole spacing on the PCB lines up almost exactly with the spacing of the holes for the TO-220 semiconductors (regulators or power transistors, I think) that were attracted to the chassis previously
• a screw post block taken from an old abandoned mixer

I still need to add a couple of small panels to attach input and output jacks, but it's usable as-is, and I'm very much looking forward to breadboarding the four band comparator fuzz that I've drafted up a schematic to
