CAT5 straight through does work, but you must check the pinouts to make sure it's a passthrough, pin 1 goes to pin 1, 2 to 2, etc. So you'll most likely want to crimp it yourself.
Plus you can get all the hip new designer CAT5 colors and color coordinate for the occasion!
I gotta crimper and tester if anyone needs to borrow. I used to do that for a living.
