Unlike the Mac Minis that were available in the past, Apple’s new, cheaper $499 Mac Mini that Apple unveiled at its special event last Thursday reportedly has soldered-in RAM, making it non-user upgradeable.
This is not a nice choice made by Apple. On the other hand, users are still able to upgrade the RAM that their Mac Mini would have when customizing their device through Apple on their online Web site (if they want to). The basic model runs at 4GB of RAM and is upgradeable to 8GB or 16GB. The higher-end models run at 8GB of RAM and are upgradeable to 16GB.
While the device’s RAM may be soldered, the hard drive is still removable and user-upgradeable.
