Pump - I've used the ultra
in all my builds since I've joined. It's still going strong. Just get it!
Rad - I have used a few makes and sizes (singles/doubles/tripples) and I settled on a pa120.3. I don't think the make of rad makes much diff tbh... Just cpu in the loop, decent single or any double rad will do. CPU and gpu any generic tripple will do, imo.
Block - personal taste, they don't cost much ~£30-40 so just get whatever floats your boat.
As for the rest, looks alright. Really depends on what you are going to do. If you just surf and game get a cheaper dual core and spend more on your GPU.
