I’m currently looking at budget microATX cases for another build, and once again I see some very common very easily avoided bad design choices. And I even see many of these bad designs in more expensive cases, too!
Most notably for me:
A PSU intake inside the case right next to the case’s rear exhaust fan, so that the PSU actually ends up pulling air in through the case exhaust fan
A PSU intake that (hurrah!) intakes air through a bottom case vent, that either has no filter or one that cannot be removed for cleaning and replaced without lifting the entire case up (gah!).
A righthand side panel that has no room for cable management, or what looks like some room, but ends up requiring squishing cables just to get the damn side panel on, with sometimes even a noticeable bulge afterwards if the panel is really cheap plastic.
Drive bays that are not accessible from the side, and are blocked by a CPU cooler with a tower heatsink (or other internal hardware). I hate that so much!
Front fan mounts with such tiny clearance under the front panel, and vents so small with such right angles, that airflow is seriously impeded.
I wonder: what design choices do you folk run up against time and again, that make you grimace?
