I need to rack-mount a pile of assorted small embedded devices (weather monitoring, stratum 1 clock, ADSB, AIS, assorted devices used for kernel test builds, ethernet serial bridges, and all manner of other stuff) that currently take up about 3m of bench space. Unfortunately no-one makes racks for things the size of a book, and looking at various things that could pressed into service, e.g. steel mesh paper trays, hasn't turned up anything useful, at least not that you can get in NZ. So it looks like the best bet is to roll my own using alu stock. The idea was to build a series of shelves using alu angle and bar stock and put alu mesh over the top for the devices to sit on, as per the incredibly high-tech CAD drawing below:

 

 

 

 

Then I'd assemble a bunch of these shelves into a rack using more alu angle as legs.

 

 

Does anyone have any thoughts on this? Is there a better way to build up the shelves? Does someone make ready-made miniature-size equipment racks of this kind?
