At the Denver Synth Meet, Synthrotek officially introduced a new line of 1U Full Row Eurorack-compatible modules and a 104 HP Waterproof Case.
The 20 and 24HP sized modules are designed to you can completely fill a 84 or 104 HP row case, with no extra modules or blank panels needed.
Here are introductions to the individual modules:
The 1U modules are expected to be available March 27th, as complete factory assembled modules, kits and PCB/Panel combos.

Makes me wonder what crazy thing you are doing to need a waterproof case.
Although be great in shipping (like we trust all that ship)
