I'm a newb to all this also and from what I've gathered from watching the forums for the past 3 weeks is that its best to build your own. Every kit has a part that isn't the best. The set up that I have ordered is
Danger Den Maze 2 waterblock
Hydrothruster 500 QV pump
Aquacoil radiator
making a reservoir-like rig that trilobyte made which can be seen here

Its like half inline half reservoir. Just need to figure out how to get the parts in the US in a small town =(
After that all I'll need is a computer to put it on lol.
