Crappy desk layout. My office has a long “custom” multi station desk and each station has a certain amount of leg room for chair etc. The compact mid tower shares that space. It gets to feel intrusive and “in the way”. Yep that’s no fault of the tower at all (and a desk problem and not a computer problem) but there’s many times I wish I could just get rid of the box down by my feet and put a tiny one behind my monitors.
