Custom Watercooling, Help!!!

[Dreaded_Cheese]

After finally figuring out what I wanted for my build, I thought as I am already spending £800, I may as well go one step further and add watercooling. After looking at all of the kits I finally decided I was either going to get the Swiftech H20-220 Apex Ultra or a custom kit including the following:
Swiftech MCRES-Micro Watercooling Resevoir
Swiftech Laing MCP655 12 VDC Pump
D-Tek Fuzion Universal CPU Block
Alphacool NexXxoS Xtreme lll Rev2 Triple Radiator

Now, I assume that they will all fit together, however would this custom kit be any better than the Apex Ultra? Also, I know I need to add tubing, what size? And also what sort of barbs will I need, (would these do)
Could anybody improve on these parts? The maximum I could possibly spend would be about £180, not including the de-ionised water. Thanks.

got pretty much the same custom spec as the one your looking at apart from the rad and i would change it to a thermochill as there worth there money check my sig for the link to mine incase it helps

go for 1/2 barbs and 7/16th tubing as its a great fit
