Just curious if anyone else here leaves their case(s) completely open on the side. I have three computers running right now (2 with old, junk parts), and I leave all three cases open on the side cause I'm always tinkering with something, and it's a pain to have to keep taking them apart. Plus, the cases are ugly as sin to begin with, being hand-me-downs.
Is this maybe a bad idea as it invites dust and all sorts of other junk into the parts? On the other hand, even with the case on, all my parts always manage to get covered in dust anyways. I'm not worried about spilling anything or kicking anything as I'm always very careful around them and keep them tucked away in a corner when I'm not messing with them.
So what do you think - am I alright leaving them all open all the time, or should I suck it up and slap the side covers back on each and every time?
Any thoughts or opinions are appreciated...
