I’d love a predrilled enclosure kit. Precut ports for a 16x2/20x2 LCD, serial, RJ-45, USB, SD card slot, DC jack, etc. Supply covers for unused ports. Sell panel mount sockets and connectors and the needed cabling to hook them up to select boards. Make a few different size enclosures to match the different ARM/AVR boards.
Yeah, I can do it myself - but it’s really tedious to make cables and I never really seem to manage to make a neat job dremeling shapes like RJ-45. Sell it to me all in a single bag as a reusable prototyping kit - enclosure, covers, connectors, cables, etc.
