I just finished installing the mobo waterblock, cpu/cpu waterblock. Here's a pic of the mobo block as request a few pages back (shot with my point and shoot, I'll use the D3S when I finish the build).
Off topic but funny. I ordered EK's RE4 last night because I was so pissed at koolance. When I woke up I cooled off and canceled the order, but then I checked my email in the evening and my order shipped. Anyways EK backtracked and canceled the order after it shipped out already (they checked their email/cancellation too late). Quite happy with their customer service indeed!
Anyways, to sum it up, very happy with the build quality of the Koolance block, but a touch disappointed with the QC (ie - Polishing the top of the block which is visible to all to behold). On a side note, I did notice that the milling marks a more how light reflects off of the block (when you take a photo of it), as apposed to it being physically rough/not smooth. Not sure how on a "microscopic level" it affects cooling, but at the very least, when I ran my fingers over the milling, it feels smooth, with no distortions on the surface. I know, I know, that's a very, very far cry from a scientific observation/conclusion, but it is an observation nevertheless.
