MOTM parts

This is intended to be a resource for doing DIY, repaneling, and/or repairs on 5U systems. At present, some of this information is very difficult to find or otherwise available. With the growth of interest in DIY for both MU and MOTM formats, it seems like an appropriate time to start this, and compile as much information as possible in a single place.

If you have any corrections or additions to this list, feel free to make them here, or send a PM to diophantine on the MuffWiggler forum. I plan to eventually add some HOWTOs, FAQs, pictures, tutorials, and schematics. When I do that, I will likely split this out into multiple pages. For the present, while it is very much a work-in-progress, let's keep this as one page for ease of use & editing.

Notes

• I'm not wanting to do a list of every possible panel part or knob (everyone has preferences), but to list the common/major/most-wanted parts in these formats, and/or what sort of things will work. I'd love to eventually list the sizes and have templates/sizes for panel design too.
