Best universal GPU block?

[Alcsi69]

Hey guys!

I want to build a GPU only loop for GPU benching, and I really liked the EK-Thermosphere until I saw I'd need to buy additional backplates and what not to use it with older cards.
I'm now looking at this: Alphacool GPU HF 14 block. Does any of you have any experience with it?

Heatkiller has a really good universal block. I cant comment on the ac block.

Yeah others also recommended the Heatkiller GPU Core X3 so I'll probably get that one instead.
