Gam3r01 :
Good luck fitting a 240mm cooler in the 200r.
Not to mention thats not "the best" anyway.
That case can fit 2x140mm fans on top so if your motherboard has enough room above then a radiator with only 2x120mm will fit just fine.
As for your best statement, it has been rated top in quite a few articles this year due to ease of installment and it's cooling power.
Although, I'm sure OP would love to have a 1000 gallons freshwater pump pushing through the case or to just have the components submerged instead of even having a case. The "best" is in my own personal opinion for this current situation.
