i couldnt see many cases making it past the IC form, it would just be too expensive to produce that many different cases in relation to mech keyboard gbuys. they would need to be like ~500usd for a gb case or the popularity factor. seems counterintuitive to purchase a case to build a pc in it just to take it apart and do it again in another.(for non rich af builders) whereas keyboards have so many different options for switches and lube and different material cases that there are so many keyboards that feel and look like a new experience, so they keep them and use them. i couldnt imagine someone having 10+ sff pcs lying around like how keyboard enthusiasts keep their keyboard builds. just my thoughts... because a low volume run would cost a crap ton to setup haha
