Hey guys. I got a lot of cables in my case. On from the PSU for the fans. 1 for the TFT Screen and 1 for the lamp. The cables are all pretty long and sometimes in the way. So I want to make them shorten, does anyone have any tips for me on how to do it?

What I usually do is cut it to the length I need and then use butt splices to splice the two ends back together.

Shrink tubing works pretty well, too, after you've either soldered or twisted
the wires together.

If you don't have a soldering iron, then definitely use the butt splicers. you just cut the amount of wire out you don't want, stick the newly hacked ends of the wire into each end of the butt splice, and crimp them down. Quick, easy, and permanent. Just make sure you use a good crimping tool and test pull on the wires to make sure it is a sturdy fit.
