There are a million case reviews out there for the case here is one of them (EVGA Hadron Hydro Unboxing - Unpacked) I have watched a lot of them but none I found actually built a water cooled system in it so I’m going to tell you about my water cooled build and what I thought about building in the case and the kit you can buy for it. Thing that I didn't like about the case the cords. The front IO is not sleeved and they need to be an inch longer. The PSU sleeving is not good at all it needed to be longer and denser or just make the ALL the cords black. That is about all about the case I didn't like. It’s supposed to be small and you know if you want or you don't want a small case.
Now I’m no expert water cooler but have built a few water cooled systems before and here is a link to the one before this one that I have built (InWin D frame old set up and new set up). say that this is what I had problems with in the water cooling kit the tubing and fittings were the two biggest problems with the kit if they sold the kit without them I could see buying it again and getting your own. Now they do give you everything you would need for tubing up a CPU loop but not a CPU and GPU loop. If you want to do that find and extra 90 degree fitting and two more compression fittings I had two evga compression fittings around and an extra 90 degree.
The tubing inner diameter needed to be a hair bigger but that would have made the tubing thinner and the tubing already kinked easily. the other thing was that the compression ring was a bear to get on I cracked my skin on my finger trying to put those rings on, they were too small or didn't have long threads on the barb to cache the ring. the two fittings that I used not from them kit I had to stretch with hot water and needle nose pliers to fit and found that the tubing will rip if not careful when having a ruff edge from cutting. The tubing didn't cut very well and I had tubing cutters that are very sharp and the anti-kink coil didn't cut nicely ether.
The loudest thing in the case after I has done was the pump and the fans are corsair SP 120 on low (700-800 RMP I think) but the pump you couldn't heir over a game being played or typing or a movie. It’s being used for a home media/ steam games/ web browser on the couch about 7 or 8 feet away and they can’t even heir it. when filing the res it has thick plastic walls and I was watching the sides of the res not the fill port and I over filled a bit the first time. hints start at deepest part of the case when staring your loop, it’s a waste but might consider buying different tubing and compression fittings, keep with a short video card it supports longer one but might be harder to find a place for the extra cords, the side panel window scratches easily, if you go with the fittings that are provided hot water and needle nose pliers will help and for the compression fittings if it in a hard to get to spot maybe use the fitting as a barb fitting with a zip tie or tubing clamp, the case and the water cooling kit are not cheap at all but if you like the idea, looks, and size of everything might be something to look into.
Where it is now? I built the computer because I really liked the idea, I have a few parts lying around (hard drive, watered cooled GTX 660, and AMD 760k), and wanted to sell it. I found a fiend that wanted me to help him build a system with a ok GPU, SSD, hard drive, quad core CPU over clockable, in a really small form factor, and the case had to be nice and simple. first told him I was building this and I would be done in a week and I had no one to buy it but he was did not what anything to do with water cooling at all so I gave him a few other list of builds and walked him threw them didn't like any of them. so a week later sent him pic of this build and he said "I want it now how much" and then " wait what’s the specs" I told him " AMD 760K, GTX 660, 256 GB SSD, 750 GB laptop HDD, 8GB corsair RAM, MSI A88XI AC motherboard, and evga water cooling kit of $______" he didn't want the price to be told but he agreed right away and I told him what he needed to watch for with water cooling. Now here the build
