The removable drive device racks give users plenty of flexibility to gain maximum interior space needed for maximum cooling performance and proper cable management improving overall case ventilation.

Unparalleled Cooling Ability

The Tower 900 has the capability to deliver excellent cooling efficiency, and enables users to build extreme air/liquid cooling systems with high-end, large graphics cards, treated by DIY/AIO liquid-cooling systems and air-cooling units.

"With such a niche and indeed unique case, our conclusion is actually fairly simple. If you like the look of the Tower 900 and want a case that's almost unlimited when it comes to water-cooling potential then it's definitely something you'll want to consider, and the same goes for those looking for a show system or who just want to cram all the latest gear inside."


The Bottom Line



Surviving our enthusiast testing process isn't a chore to be taken lightly. Every case that comes through the HardOCP labs is thoroughly examined, pushed to the limit, and tested in ways that we feel gives you an accurate assessment of the product's ability to perform in the manner you would use it at home. The Thermaltake Tower 900 is not only a showcase for your hardware, it is also a showcase for your skills as a system builder. There is no better way to put massive amounts of hardware on display and look fantastic while doing it. The design of the Tower 900 has removed the restrictions and limitations of a traditional chassis allowing you the freedom to build a truly unique system.


 "all-in-all, I think Thermaltake’s has done a good job collaborating with Watermod France to make a chassis specifically aimed at the “hardcore” watercooling and PC modding enthusiasts."



Nous voilà au terme de la découverte de ce nouveau boitier par Thermaltake. Tout d'abord, il faudra déterminer si l'on aime ou pas ce boitier, car c'est sûrement le point le plus important. En effet, si vous aimez ce boitier, dans ce cas, vous pouvez craquer. Il est bien pensé, bien équipé, propose des possibilités d'intégration folles et offre un style inimitable avec sa configuration placée dans le haut et sa symétrie. Ajoutons au passage que le tarif, vis à vis de ce qui est proposé, est clairement adapté. Alors certes, certains trouveront que les 250/270€ demandés sont de trop, mais ce boitier est un modèle XXL avec des panneaux en verre trempé, donc dans l'ensemble le prix est bien placé. Après comme nous le disions, si vous n'aimez pas ce boitier, vous le trouverez trop grand, trop lourd, trop cher. 



  • Big enough to hold nearly any liquid-cooling configuration
  • Great cooling on stock fans
  • Great isolation of our internal component noises
