This was my first computer build. I used this system air cooled but as I live in a very hot area (thanks Australia) I decided to take the plunge and go watercooled!
Note for first time watercoolers this was a steep learning curve when building in this case!
Bending Pipes: I originally bought a pipe bending kit from bitspower (excellent company and an absolute pleasure to deal with, both my orders arrived two days earlier than advertised and the company replied to emails within 24 hours) and the kit gives you everything you need and I highly recommend it. I moved away from using the 90 degree bender pretty quickly when I realized that this was often placing the 90 degree bend in the wrong place. I used a free-hand method instead and this drastically increased my success rate.
