I would also suggest the Eheim 1048. I am using it and I love it-it provides great flow rate and is very quiet. Also, it is a strong enough pump for future expansion to GPU and chipset cooling-right now I am cooling my GPU and CPU with it, and I have an huge case (the 1048 pumps the water up about 20''....)
As for a waterblock, I've always been partial to danger den's blocks (www.dangerden.com
) Heck, if you go with the second newest model, the Maze 4, it's on sale for about $35 now..
Hope this helps.
