The 2019 Mac Pro features a modular design that makes it easy to upgrade or swap out components like graphics cards and storage. Follow along for how to install more storage or another GPU with an MPX module.
MPX module stands for Mac Pro Expansion Module, and there are already third-party options to customize your Mac Pro.
