1. If you have specific inlet/outlet and then have specific ways to mount the block (with the 3 screws on the same location with the CPU lock lever), it just means there's no change we can mount it the way we want. Assuming if I want my tubings to go in from another way, I can no longer do it with this block.
2. It looks like this is very much the same like the GTZ except for some cosmetic differences on the top. Also to be honest, I moved from Apogee GT to GTZ with little or no improvements. I'd be happy if Swiftech makes a product that enables us to mount whichever direction that we want and/or at least give a reasonable improvements in temps or it doesn't justify an upgrade at all.
