The Antec P9 Window is loaded with builder-focused features that deliver performance, Quiet Computing, and future-proof expandability right out of the box. Spacious enough for eight PCI-E cards of up to 430mm in length, and with room for up to a 360mm radiator on the top, the P9 Window also features an adjustable pump bracket and removable HDD cages that enable you to install a custom water loop with ease. In addition, the P9 Window comes equipped with two 120mm fans in front, one 120mm fan in the rear, and plenty of additional mounting options. The eight tool-less 3.5in drive bays are each compatible with 2.5in SSDs, so expand and upgrade however you’d like. Don’t be confined by limits- with the P9 Window, you’re in command.
