Like most said, the electrical tape will eventually start to peel off
🙁 Happened to me.
Two things you can do to fix this:
1) Use heatshrink tubings on the ends
2) Use zip ties on the ends
where the tape will eventually peel.
Zip ties is nice and cheap. Worked well for me till I got annoyed at the way the tape left the sticky residue.
You can buy some plastic looms at most auto shops (AutoZone, R&S Strauss, etc..) or Home Depot. I picked up my plastic loom on the cheap from HD. Bought some 1/8" and 1/2".
Eventually you'll get tired of the electrical tape, and cleaning the residue off the wires is no easy task (I can tell you from personal experience.) Either go for some nylon cable sleeving, or just tuck your wires in nicely. A little time, some zip ties, and some looms, and you can make your comp's innards look pretty decent.
Here's a picture of my setup.
My setup I used a piece of plastic loom to hold together part of my ghetto rounded IDE cable (electrical taped some IDE cable) and some power cables together. Too bad after I spent all this time tucking the wires out of the way, I never bothered to check my mobo first. Just sent it back to newegg today for RMA. I'll try and hook it up just as nice when I get my new one back.
