Nice review, Mike. Too bad you didn't have an U-120 eXtreme and a regular U-120 to test too though as both of those are stellar performers, if you get them with a decent base. As for the Tuniq, you called it exactly right about the AM2 mount being an afterthought. Tuniq developed the TT120 before AM2 was on the market and the original versions (including mine) didn't have any way to mount to AM2 included at all. They cobbled together the AM2 mount some time after AM2 came to market. That's why the mounting for LGA775 and socket 754/939/940 is soooooo much better. BTW, try that TT120 out on a socket 939 Opty or X2 system and watch how well it works.
