"The ARC is a beautiful piece of engineering. I did have to mod to mount the H110 in the Top of the Case but it was very easy. I used a Dremel and cut a 1" wide and 2" deep out of the end of the Optic bay and had to drill 2 holes in the top of the casing. The 2" depth will allow for either Push Pull or the installation of a 280x60x140 rad if I ever go that way. The H110 will mount into the front with a little mod for the 20mm Fan Spacing but I wanted to keep that space free if I ever decided to get back into GPU cooling and run a separate loop.
Even with the 140mm Rad width I ended up with loads of space above the MB and sufficient clearance to run a DVDRW in the top optic bay - Looks great ;o)"
