I might put in another 570. Just want to make sure this is fine before I order. Oh and the ECO lasts up to 50k hours?

You may as well order the system pre-overclocked given that you've chosen the k processor, high frequency RAM and liquid cooling.

It's otherwise fine.

In theory the ECO A.L.C should last ages yeah.

I will overclock once warranty runs out. It's so I can make it run faster later down the line if I really need to.

 

[Tom DWC]

Fair enough, remember if you order it pre-overclocked the warranty covers the overclock though (and you can always take the overclock off).

Plus you can then order better thermal paste (which I would recommend).
