Taking plunge going to water cooling

[murphy7801]

Hi guys built PCs for years never water cooled wanted some input see if making any rookie errors.
I have an NZXT switch 810 MSI x79 big bang 2 and soon to have reference MSI gtx 780 or 2. To cool these I was going to buy:

With the XSPC gtx 780 block and back plate

I wanted to use compression fittings:

Now if I went for second blocked 780 I was thinking of putting 280 rad in front of the case would pump be enough is anything Iv overlooked?

a 420mm skinny rad to cool a Cpu and 2 Gpus? It's possible but temps will be quite high and fans needs to be running at higher rpms to cool it down. Go for a D5 RX 360 kit and then buy another rad for the front which could be another 240mm RX or Alphacool UT/Monsta rads. A 360/240 rad setup will easily run at 7v and 5v if you really wanted.

Yer If I went with second gpu I would stick 280mm rad into the loop.

120's are better IMO. Better fans...

Go for thicker rads as you have the room and a skinny rad in push/pull will still be behind in temps vs a thicker rad.
