After watching many videos where the 8-bit Guy and Adrian Black remove adhesive gunk from computers with a heat gun I decided to try and remove the leftover double sided tape from a C64.
The heat gun worked wonderfully on the adhesive gunk - however, I was so focused on the gunk and happy that it was working I failed to notice that the non-functional vent slats were catching all the hot air and self-destructing.
This was with the heat gun on the lowest setting! I guess I'll have to use that white Kickstarter case I was saving in the closet for a build.
