Second PC Build

I am planning on doing water cooling as it will be great to get some experience with watercooling.  I would not go mad with the OC but I like the aesthetics of watercooling a lot more than an air cooler/ closed loop cooler.

Also, do you know of a good gaming monitor I can get for around £200?  Anything from 27" is fine

Gaming monitor i dont know but im sure someone around here might have some recomendations for you.
