Parts for watercooled G5

[Armada]

I started planning to redo my Powermac G5. I had a h100 in it. But it died a few weeks ago.

Now i am considering wasting 400euros on an awesome custom loop. It would only be for my 3570k and a 670 or 880 depends on how much i waste in the steam sale. 

 

I already choose most of my parts. Currently i am struggeling on deciding radiator size.

It would go in the bottom of my G5 where my psu is located right now.

I can fit a 360 most likely but I am not sure wether i should go for 30mm, 45mm or even 60mm thickness.

I have about 9cm from bottom to mainboard but also need space to hide my 8pin.

Would I need a 60mm to cool properly or is 45 enough?

Sorry for the bad pictures. Didn't feel like making it look pretty for you

 

yes the fans are held in place by tape. Don't worry i had the h100 screwed in.

I had nearly all cables sleeved but my old psu died on me 2 weeks before the h100 died.

I am going to sleeve them again when summer holidays begin here in germany and I dont have to sit in school everyday.

The red and green wires are going to my ghetto powerbutton but that problem i will safe for my next post.

 

Here you can see the space in between psu (nearly the same as 60mm rad with fans) and mb

 

But I also can't decide on fans. I really dislike my Sp120. They did the job but sound like a starting jet.

Should I go for the Nf f12 or the nb eloop (http://www.aquatuning.de/product_info.php/info/p14175_Noiseblocker-NB-eLoop-B12-PS-Bionic-fan---120x120x25mm--.html)

They are about the same price but both are stupid expensive. The nff12s cost about 22euros while the noiseblockers only cost 18.

 

I hope you will thake your time to read my post and help me with my problem. I will also start a build log when I actually start my built

45mm is sufficient.

Go with the NB E-loops, but in push only, they are dead quiet and push a tonne of air.
