I did this a lot as a kid, up to the point where I just didn’t care about having a case anymore. I completely removed the whole thing and put it on top of a rubber plate, and covered it after use with an old horizontal metal case from a 486 or something. I loved how confused my mother and then later my girlfriend would look when they saw me working/gaming in that total barebones setup. To be honest I have very fond memories of it and would definitely do it again if I didn’t have two small kids!
