Apple recently updated the Mac Mini with a brand new iteration that costs just $499. We already learned that the RAM is, unfortunately, soldered down. That means you should configure the device with as much RAM as you think you’ll need, since you can’t upgrade it in the future. iFixit has now done a proper teardown of the entire device, giving us an even better look at the guts of Apple’s most affordable OS X Yosemite computer.
iFixit said that the Mac Mini employs the smallest Torx screws “it has ever seen,” so make sure you have a TR6 Torx security screwdriver before you even get started. iFixit found that the Mac Mini includes a quieter fan than the previous model, thanks to new advanced hydraulic bearings included in it. The team also only found one SATA port, suggesting you can’t add another hard drive, but that it might be possible to add another “slate SSD.” iFixit said it’s going to wait until it checks a Fusion version of the Mac Mini before it makes a final claim. Also, Apple hasn’t changed the power supply in the Mac Mini since 2011.
iFixit ultimately gave the Mac Mini a repairability score of 6/10 because it didn’t have a lot of glue around to mess with. Unfortunately, though, you’re definitely stuck with the RAM and CPU you choose when you configure the system, as neither can be swapped out in the future.
