My ever changing PC in the Antec P180 [a little 56K unfriendly]

[perfection]

that's okay, the pins on my Apogee are look alot larger than the GT so that's how I figured it out. I didn't buy it, it was given to me as I upgraded from the Swiftech Storm.
I'm thinking of getting a D-Tek FuZion as my next waterblock upgrade, FuZion is one sexy block and the GTX is not bad either but I'd rather prefer the FuZion

Oh, you have the original Apogee? Sorry, I was assuming it was the GT as the Apogee wasn't in production for very long. In any case, the difference was on the inside, not the outside, so it's irrelevant.

As far as I can see, yes. This allows them to mount their Apogee GT with the inport and outport in a vertical line, which the regular mounting plate of the GT will not allow you to do. I'm not 100% sure though, obviously, as it wasn't me that did it and niksub hasn't posted here.

yes you can change it to a vertical mount, its because the LGA775 mounting is a square shape so you can mount it anyway you want

right now, I really couldn't be bothered, I'll do it next time I open up my PC
that will happen when I change out the motherboard and fans on the radiator
