Mini-ITX, Micro-ATX and heck, even ATX chassis are great, but they?re just too small, at least for some builds. What do you do when you need to fit an absolutely ridiculous amount of hardware into a single build? What if you have the biggest graphics cards money can buy, gigantic water cooling radiators, huge amounts of storage, multiple PSUs and more that you want to fit into your chassis? You get an absolutely freaking huge chassis, that's what you do!

Thermaltake are known to make quite a few monster-sized chassis and one of their latest efforts, the Core X9 is certainly one of the biggest. Not only is this chassis big to start with, but it comes with a rather cool feature that allows you to take two or more of them, bolt them together and make it even bigger. This means it's possible to have one system which spans both chassis, or even simply stack multiple systems, the choice is yours.

The specs are not for the faint of heart, with room for E-ATX motherboards, a huge amount of storage drives and a dizzying array of cooling configurations.
