well I think there’s many different avenues to take on this build, I did as much as I could with the tools and parts available at a minimal cost, didn’t exactly end up cheap though as per usual.
The silix case is ok but has many drawbacks as manodeoro mentioned,
like the bigger than “gen” rehaut, and have to glue the plexi, weld, or some drastic machining.
A cartel case would solve that but then the case shape is off by a way!, even with fernaggling and shaping .
i’d pick what you’re happy with and try work around the obstacles that you’d find easier .
