What makes the best PC case for water-cooling builds? It's all about size, radiator support, and how easy it is to build custom water-cooling loops inside the chassis. We've rounded up our favorite PC cases that will go well with a water-cooling loop, allowing you to push your system and creativity to new highs.

Thermaltake Tower 900

Showcase: Thermaltake Tower 900

Staff Pick

Our favorite case is the Thermaltake Tower 900. I mean, just look at it. This is a PC builder's dream to put together a water-cooling loop. You can even run multiple loops, one for your GPU and the second for your CPU.

Corsair Obsidian 1000D

Super Tower: Corsair Obsidian 1000D

Corsair's Obsidian 1000D is a beast of a case. You can technically install two PCs inside this case with two power supplies and more. If you wanted to create a truly unique-looking standard tower build, this is your case.

Thermaltake Core P3

Wall Mountable: Thermaltake Core P5

Thermaltake makes some of the more compelling cases, and the Core P5 is about as unique a case as you can get. Think outside the case for once and mount it to your wall. Just watch out for dust since it's completely open.

Cougar CONQUER 2

Easy Installation: Cougar CONQUER 2

The Conquer 2 from Cougar is brilliant, especially if you prefer some open space to get your water-cooling loop just right. The inside tray can be removed from the outer case, allowing you to install everything before sliding it into place.

LIAN LI PC-O11

Small & Mighty: Lian Li PC-O11 Dynamic

Lian Li makes some amazing cases, and the PC-O11 Dynamic is yet another fine example of the company's craftsmanship. It's a mid-tower case but can only hold up to a MicroATX motherboard, meaning you'll need to be smart with how you make your loop.

Phanteks Enthoo 719

Impressive Design: Phanteks Enthoo 719

The Enthoo 719 is a stunning case from Phanteks that allows you to go all out and customize your water-cooling rig with plenty of handy features. You can cram plenty of radiators inside, run multiple GPUs vertically, and have two systems with dual PSUs.

The best PC case for water-cooling

If you're looking for a case to help you showcase your system build, the Thermaltake Tower 900 is a case you should strongly consider. It's a gorgeous chassis that can support two reservoirs and pumps for separate loops, one for your GPU and another for a CPU, allowing you to create some awesome-looking results.

Prefer to work with a traditional tower chassis? The Corsair Obsidian 1000D is probably the better option, rocking a more subtle look than the Tower 900 from Thermaltake, but still allowing you to pack so much inside. You can even go all out and install two PCs inside.
