This is the first water cooled build I've done, and the second build overall. This was more of an "upgrade" than a build, as I slowly replaced all of my old components until I essentially had a completely new computer.
Initially when I purchased the Phanteks Evolv ATX Glass case, I was just planning on upgrading my case and nothing more. However, once I received the case and transferred all the components from my old case into it, I realized they didn't do it justice. The tempered glass looked amazing, but the average components inside made it look just "meh". Not only that, but the fact that all the cables in the back could be seen meant there was only one thing I could do -- build a beast of a gaming PC with the most immaculate cable management possible.
I knew it would be a challenge, but my goal was to make the back of the PC look just as good, if not better, than the front. The first thing I did to help accomplish this was to get rid of all the unnecessary cables. I ended up taking out the front USB header cables along with the cables for the microphone and headphone inputs. That helped get rid of some clutter in back, but it wasn't good enough. I knew having all the fan cables running to the fan hub in back wasn't going to cut it, so I hid them in the only place that's hidden in this case -- the top. The biggest help in getting the cable management as good as I wanted was the custom cables from CableMod.
When I finally decided to try doing my own custom loop, I knew I had to do something to compliment the cables in the back of the case. With some luck, it worked out that I was able to route the tubing through the back of the case. The only drawback to how I currently have it set up is draining the system. The drain port isn't at the lowest point of the system and a good portion of the fluid doesn't come out without some help. It's a bit of a pain, but I'm able to drain the rest by hooking up a piece of soft tubing in a couple different locations and blow the rest out.
I'm quite happy with how the build turned out. The only noticeable flaw (that I see) is the tubing in the back above the SSDs and next to the drain port. The tubing sags a bit so it's not a nice horizontal line and subsequently it leans a bit to the left going up, but I'll probably end up fixing those at some point.
