I used Cat 5 to wire my cabinet. The most difficult part I found was that the internal ethernet strands are...what, 24 gauge? 26 gauge? Whatever the size, my wire strippers did not not do that small. When you open up the Cat5 cable, you'll notice that the wires are twisted together into 4 pairs. I found that if I left the strands twisted together and stripped both at once, it worked better. It still wasn't very elegant, but it worked alright four times out of five.
