This is my first custom loop and it didn't come out quite like I wanted in regards to getting the bends somewhat close but its functional! I have been working on this project for a while now and have thoroughly enjoyed the whole process! The system has been running great for a few months.
I had issues with how I was going to route the water to the back. I ended up using a step bit and bulkhead fittings to pass through on the sides. Other than that and the bends, everything went incredibly smooth and I'm very happy with it!
