Looking around for a slim case, the only information I found was on reddit. https://www.reddit.com/r/buildapc/comments/75vnnz/good_slim_atx_cases/do9h6vm There is 1 matx case that takes a normal atx psu is Bitfenix Pandora is 160mm. Which btw is discontinued. Given that normal ATX have no 5.25 bays anymore, why are they still the same 21cm wide? Given 16cm can house ATX PSU, why are 14cm cases like the Core G3 using SFX PSU? Is there a reason nobody makes thin ATX, w/o the need for pcie header leads, etc? I see fat and short ones, but I don't see the point of 21cm width when we're putting nothing wider than the PSU there.
