I am a full Z4 kit owner so I think I will reinsate my point.
I live in Canada, so I was quite limitied in choices, and I wanted to stay with the same supplier (e-Compuvision) because they had helped me in the past. So, I ordered the basic kit (block, rad, res, tubing, shim (very nice shim though))
I have used it scence two weeks into january. In the beginning, I was quite happy with the results (compared to the bloody sk6 with a delta on it) but then I started to look around. Their had been two Very Very good reviews on some reputable websites, so I figured my purchase was sound.
Now that my system is slightly aging (1.33 T-bird @ 1.52, 512 ddr, Geforce 3) (yeah I know, thats still really good) so I wanted to push my computer farther, then I noticed it.
The temps were quite high and I couldn't push my processor any farther (avg oc is 1.6 with my stepping). So I was looking around and found here, read this whole thing while is was only 5 pages long, and came to a conclusion.
The block has flaws, big ones, no hiding that, but if you are happy, you don't need to go out and replace the whole thing. I am not happy "Anymore" so I am getting a maze3 later in the week.
I do though, enjot how it looks, so I may pick up some arctic silver adhesive, and use the block as a northbridge cooler... Any thoughs on this?

Btw, read my sig.
