Wow I'm impressed with that Fractal Design Arc Midi R2 case review.
Hardwaresecrets say the R2 supports rads up to 240mm long where the H110 is a 280mm rad that is actually 301x140x30 / LxWxH with 20mm fan spacing - I Wonder?
Man I wish I had your pricing - Prices Canada for the R2 are: NCIX CA delivered $129 and NewEgg CA $142 - I can get a Carbide 500R for $125 shipped from DirectCanada. On the other hand I can get a Bitfenix Shinobi delivered from Direct Canada for $69. I know there is no comparison in quality between the Shinobi and either the R2 or 500R - The Price reflects this; but, it appears that the Shinobi can handle the H110 on top but not the front.
The only case within the above price ranges that advertizes H110 compatibility without modifications is the Carbide 500R which, in my opinion, at $125 is a sturdier case then Fractal. The 500R is an older case but has all the modern features.
PS:
Well it seems some uTube Reviews say the R2 has support for 2x280mm Rads (Top & Front - NICE) but only for the 15mm fan spacing such as the NZXT X60 (I believe the X60 rad is around 296mm long compared to the H100's 301mm length - If that matters). I suppose it would not take much of a mod to adapt to the 20mm spacing for the H110. I like the Top Rad offset clearance of the R2 for the MB but not fussy about Top Controller location. Very NICE INDEED.
It appears to me the Corsair H110 Rad has specific 20mm spacing for their own casings and fans where something like 2 Noctua NH-P14 FLX fans may fit the Rad but not other cases (Correct me if I'm wrong). A thin fan mount relocation plate bolted to the rad or Drill the Casing would be a rather simple Fix but at $40 a pop, them Noctua's will defeat my purpose.

Eat your heart out Linus ;o)
I can't see why you could not fit a Corsair H110 into either the Top or the Front of the R2 case - Specifically the Top with minor Mods. Guess you have me leaning toward the R2 - TimeToLiveSavings or I will opt for the $70 Shinobi for 1/2 the price ;o)
I'm running 16G's of 4X4G's of Low Profile Samsung MV-3V4G3D-US Green @ 1866Mhz 9-9-9-24-1T @ 1.2v on an Asus P8Z68V-Pro Gen3 with an i7 2700K at any Speed / an old EVGA e-GeForce GTX 280 / XFX 850W Pro Black Edition (Into Video Encoding) - Win7 x64 Ultimate SP1.
Love that RAM
Here's a descent Bitfinex Shinobi Water build that positions a RX240 (124x63x280mm) rad in the front at the expense of the HDD Brackets.
http://www.youtube.com/watch?v=f5nHV8YrDv8 . He does appear to have room at the bottom to mount 3 HHD's between the PSU and Rad if he wants. I sure a 280 AIO will fit there as well. Is there is enough room in the Shinobi Top to mount a H110 280x140x30 rad close as possible to the front side case for fans to clear the mainboard or do I mount the 280 rad in normal position and simply mount the fans on top and cut holes in the top Filter - Hum?
