The radiator isn't the greatest quality (and read a few posts about it leaking eventually), and the pump included in the kit you may as well throw in the trash. Also, the included fans aren't that great either. Otherwise, the fittings are fine (and they are cheap to purchase anyway) and the tubing *shrug*
I originally bought a kit myself when I first started out, and I replaced it in 3 months time because it just wasn't good enough versus air cooling performance and noise wise... outside of the fact that I could now cool my GPU with the loop too that helped reduce noise from the GTX580 fan.
For the fittings if you can swing it, go with bitspower instead of the danger den. I found them to give a bit better grip on the tubing, and be of better quality. Otherwise, your list looks good there! (just don't forget a few clamps, and some tubing) Also, for the pump.. I bought a DDC pump (MCP35x) originally, and I switched pretty soon to a D5 Variable speed pump. Very very quiet, and I found it easier to mount properly and get rid of vibration without worrying about heating up the tiny DDC pump. Just another thing to consider... probably get a bit more longevity out of the D5 pump because it is self-cooled etc. in my opinion. Read up on that, but again... your pump is something you can keep for a long time as well as the rest of your major cooling components so take your time and buy the good stuff so it will last Edited by chorner - 7/25/11 at 9:29pm
