The MSI MEG MAESTRO 900L PZ Concept Case Series was revealed a few days ago, coinciding with CES's kick-off. Later on in the week, TechPowerUp took the opportunity to absorb these voluminous (900 liter) prototypes—other press outlets have expressed great enthusiasm about MSI's extremely bold approach. It is not clear whether these new models will reach retail—the MEG MAESTRO-700L-PZ (700 liter) case managed this feat last year.

The first demonstration sample spotted by TechPowerUp formed the basis of MSI's "MEG PC Build"—filled up with the AMD Ryzen 7 9800X3D CPU, MSI MEG X870E motherboard and two GeForce RTX 4080 SUPRIM X graphics cards. Lots of RGB-lit cooling solutions surrounded this hardware cluster—including the MEG CORELIQUID S360 and fifteen(!) MPG EZ120 ARGB fans. MSI's MEG Ai1600T PCIe 5 PSU is tasked with keeping this setup alive—it was up and running, as evidenced by being connected to a nearby monitor. TechPowerUp then checked out the other working prototype—a very snazzy case modding project that houses two PC systems.
