MSI MEG Maestro 900R Featured Build

For our latest Featured Build, we’re going all-in with some of MSI’s most extreme hardware, including the massive MEG Maestro 900R chassis, the flagship MEG X870E Godlike X Edition motherboard and an RTX 5090 Suprim Liquid graphics card. CPU cooling comes courtesy of MSI’s MEG CoreLiquid E15 360mm AIO, and the system is powered by the MAG A1200PLS PSU. It’s big, it’s powerful and it’s completely over the top… so let’s get this monster build underway!

 

Case: MSI MEG Maestro 900R – Available HERE.

• A Showcase Chassis: The MEG Maestro 900R uses a centre motherboard layout combined with three-sided panoramic tempered glass, placing high-end hardware into the focal point of the build rather than hiding it away inside a conventional box.
• Flexible Building: A detachable motherboard tray can also be rotated into four different orientations, giving builders freedom to prioritise aesthetics, airflow or simply make the assembly process a little easier.
• Built for Extreme Hardware: With support for up to 14 fans and dual 420mm radiators, along with vertical GPU mounting and included PCIe 5.0 riser cable, the Maestro 900R has the hardware support you'd expect from a flagship full-tower case.
