G5 Heatsink Comparisons

[Methanoid]

Does anyone have any resources showing differences (if there are significant ones) between heatsinks, as I am considering buying a cheap DP "donor" to source two heatsinks to do a conversion like this one

I am concerned that screw holes etc might be located differently and all I KNOW is that 2.0 DP heatsinks worked for the thread poster. I've got offers of cheap 1.8 DP and 2.3 DP less cheap

I'm also interested in this. I'm going to try and convert a LCS to AIR cooled in the next 3 weeks or so
