nice case looking here http://www.techpowerup.com/reviews/Corsair/Obsidian_650D/4.html
yes that looks a nice thick rad and probably the best you can do....being a thick rad you will need fans with a hi static pressure....it should cool any cpu no probs but if you needed to cool say 2 big graphic cards you can all ways put a single 120mm rad in the loop at the back of the case as well

fans i have 4 like this they are very good. cooler master sickleflow. no tek speck on ukoc but thay push 2.96 mm/H20 and 67 cfm VERY good at the price http://www.overclockers.co.uk/showproduct.php?prodid=FG-013-CM

or Corsair SP120 Static Pressure: 3.1 mm/H20 63 cfm ://www.overclockers.co.uk/showproduct.php?prodid=FG-007-CS&groupid=701&catid=2331&subcat=

Have a search on the forums - there are a fair few builds on here using the same case

I have a 650D with a custom loop in it.

Your maximum rad thickness with one 25mm fan is 47mm. I have an EK rad 47mm thick with fans mounted to the top and it is literately as far as you can go without going over the motherboard.

The Black Ice Extreme II Dual 120mm Radiator is 43mm thick so you would be fine and probably a little better off if you nwere to get a motherboard with a few fansy heatsinks at the top (before i changed to watercooling the MOBO my Asus formula Z heatsinks wee touching my fans mounted to the 240mm rad)
