Advice on Pump and Block

[Elfear]

After reading through this forum for awhile I've narrowed it down to a few pumps and waterblocks. This is my first WC setup so I'm a complete noob.

I'll be using a very large heatercore (can't remember the dimensions of the top of my head), possibly two depending on how well one works out. The WC setup needs to cool a 3700+ SD and an X850XT PE.

Here are the blocks I'm considering:
D-Tek Whitewater
Swiftech 6002-64
Danger Den RBX

Here are the pumps:
Swiftech MCP600 (Leaning towards this one, found a used Rev. 2 for $60)
Eheim 1250
AquaExtreme 50Z (same as MCP600?)
Hydor L30 (probably go well with the Swiffy 6002 since it's not very powerful)

I'm on a pretty small budget so I don't mind giving up 1-2C if the price is a lot better.

What do you guys think?

All of those blocks are fine.

The Danger Den RBX and D-Tek Whitewater are almost the same; the Whitewater is slightly better but you won't notice the difference.
The RBX/Whitewater will perform better at higher flowrates than the MCW6002 but you'd need at least 400+ LPH. I don't know what your system looks like but in a typical loop none of those pumps will make 400LPH; they might get very close though.

Personally I think Hydor is crap.
AquaXtreme 50Z = MCP600 Rev 2. These 2 pumps will perform slightly better than an Eheim 1250; however they also make slightly more noise. Just like the blocks the choice is up to you.

So with the pumps I've selected it sound like I'm better off going with the MCW6002.
