I recently upgraded the system from a Gigabyte GA-Z77X-UD3H with a Xeon E3-1240 to an ASRock Z97 Extreme4 with a Core i5 4670K. I wanted to wait for the 4690K, but I was a bit impatient. I originally had a Corsair Carbide 300R, but I ran into a snag after purchasing my H105 from NCIX. I found out that there was not enough clearance between the radiator and the VRM heatsinks. So this led to me buying the Level 10 GTS SE. It was not my preferred choice, but it was the only case that the local shop had at the time. I may replace it with a case from Fractal. It definitely gave me a wake up call and more experience when it came to dealing with Closed Loop Coolers. Research first....
