What do you do when there are no decent computer supply stores in your area?
You improvise....and use stuff from Auto Parts stores.
The sleeving (except for the cables going to the motherboard, which I'm going to sleeve once that stupid ATX pin extractor comes in, along with my PET sleeving) was all done with spark plug covering. It was actually good stuff, the fabric is pretty good quality, and it came with it's own heatshrink.
I then decided, because I was bored, to paint the molex connectors and the heatsinc fan, so I used....Duplicolor automotive spray paint in "Toytoa Silver". The cathode and fans were all there before I started my little makeover.
