Haven't bought the 120 yet, but I've already decided on it (spent way too much time researching on it to not buy it).
Btw, how is the push pull setup? I've heard mixed reactions about using two fans for the TRUE.
About the Scythe S-Flex fans, what's a good RPM for the perfect performance/noise combination? They have 800, 1200, 1600, and 1900.
