It's an old Pedaltrain Jr. and the iM2400/1520 case.
I've had the board for ages and was sick of babying it with the soft bag, especially as the value of the pedals attached grew.
I looked at new and used prices for the Pedaltrain hard case, and it seemed crazy. Started poking around the Pelican website, found a good match by dimensions then started searching. Found a super cheap, well used but more than capable option for under $80 on eBay. These things are used in vast quantities out in the world in non-music applications. The seller I got mine from still has a bunch.
