This is a really fantastic build for your first time. Did you do it all yourself? I recently built my first PC this past winter. I wanted to do a custom liquid coolant setup, but the store clerk convinced me that it wouldn't be worth the hassle, so I ended up purchasing a pre-built/ready-to-install radiator. Did you find the coolant process to be exceedingly difficult at all?
