Come visit our two show rooms, located in Schaumburg, Illinois, and Milwaukee, Wisconsin. Call ahead or feel free to drop by and see our inventory of approximately $500,000 in spare parts. We also inventory a large number of machines, always powered-up and ready-to-go for training, demonstrations, feasibility tests, and whatever else your need may be. We would love to show you around.
MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.
