After the new-but-not-very-fresh iPad mini 3, the most disappointing part of Apple's recent show-and-tell was the $499 Mac mini -- the RAM is now soldered in, making it impossible to upgrade. iFixit has just revealed that the model has other user-unfriendly features as well. While access to the RAM used to be dead simple, it's now guarded by a metal cover held in place by Torx TR6 Security screws, which require an exotic tool. Adding a second hard drive is also, er, harder, since unlike past models, there's just a single SATA port (though you may be able to install a PCIe SSD). Finally, as mentioned, both the RAM and Intel Core-i5 CPU are soldered in permanently. That's not very cricket on Apple's part, considering that past Mac minis were a breeze to access and update. Still, thanks to a lack of glue and easy disassembly with the right tools, the iMac eked a passing repairability grade of 6 out of 10.
