This is actually a simple exercise but if you are not a handyman and have the right tools it might get annoying. This is why I am trying to organise a groupbuy for this side panels.
This is what it is all about. A prototype of a 3U side panel for fixing the rails on a rack (still missing the drillings for fixing). Sure, you can fix the rails directly on the rack, but using the panels is way more elegant.
You will find more details on Muffwiggler or on the German Sequencer Forum. If you have questions just leave a comment or send an email
