There you have it. Here is a portable powered board with some custom tailoring for under $100, good luck finding that at your local music store.
The power supply is noise free and has been running great. I may do a check to make sure my regulators aren't creating too much heat, possibly burning insulation from adjacent wiring, in which case I'll add a few "speed holes"
I found some right angle dc power cables on ebay and made a few custom length power runs ($6 for 10 'ends', made 5 cables). Also got some right angle 1/4" jacks ($12 for 10, made 5 cables) and using a broken old fender instrument cable I made some custom patches. Really cleaned up the whole setup and left alot more space, things aren't so cramped.
I'm going to add some kind of clip or strap on the outside top of the box that will hold the power and in/out cables when traveling.
Replacing the latches with a padlock-able one.
Replacing the handle with something a bit more robust. The poker set was quite heavy so I'm not too concerned about the support of the box, but in a situation like this there are plenty of room for upgrades, and plenty of money saved from not spending the $300+ dollars on a powered board and flight case.
I realize I compressed a pretty big build into just a few steps (still new to this instructable thing), if you want clarification on anything leave a comment, that way others can get an answer too.
Good luck and happy building DIY'ers!
