Here is something I have been working on : Hypex UCD400 monoblocks with SMPS400 power supplies. The build itself is rather simple and very straightforward. So much so that I have to wonder if this really belongs in the DIY section. The biggest hurdle was mounting the UCD400 modules to the Ghent-Audio case as the case is to low to mount the modules directly to the chassis. I decide upon a L-bracket and seem to work fine, while also giving plenty of clearance around the module. I have now tested them a while and have been very pleased with them.
