The best PC case for water-cooling

Why you can trust Windows Central Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

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.

We also rounded up what you need to build a custom water-cooling loop for your PC if you're not sure where to start.
