I used to modify PC cases. I would spray paint beige cases silver or black, install toggle switches for fans, cut big windows in the case side and mount a piece of perspex, finishing it off with a bit of car window trim. I’d install cold cathode lighting so you could see inside. Blue and green were my favorite colors.
There were some good online suppliers of fan guards that would replace the standard grill with a laser-cut biohazard or dragon shape. There was a whole range. They looked great over LED fans.
I used to buy most of my modding supplies from DIY stores and car repair places. I once went to a hobby store to see if I could fit a PC’s internals into the plastic shell of a toy car, but I didn’t get far with that one.
I did manage to build a PC into a metal briefcase. I added a switch that required a key to turn it on.
