Yes it is TC spacing.

As far as the "Great Rad Debate", no one can claim the price/performance crown that Switech Rads have. I have PA120.3 and a PA120.1, both solid construction no doubt, but if R3 hadn't given me the sweet deal on the PA120.3 and I hadn't picked up the PA120.1 from Microcenter for $50, I wouldn't have gotten either. TC and TFC are both out of my price range for something a MCR320 or MCR220 will do at a third the cost. I will say this though, TC's and I assume TFC's rads are the same with this, they hold their value unlike Swiftech or HWLabs rads. You will rarely see a PA120.3 used selling for less than a $100, whereas you can almost always find a MCR320 used for $30-$40. It's like anything else, you get what you pay for............well, except for Swiftech, they are definitely the value king.
