Reasons you shouldn't buy a Mac mini: It's not easily upgradeable

Before the Mac mini was updated in October, one of our reasons you should buy a Mac mini was because Apple made it easy for owners of the 2012 model to replace and upgrade elements such as the RAM for a memory boost. It meant that the Mac mini could become an upgrade project, and if you were unsure about what specs you needed you could rest assured knowing that you're not going to be stuck with them forever.

Now, however, Apple has put tamperproof screws on the underside of the Mac mini to make it much more difficult to upgrade. It's not impossible, but it takes quite a lot of effort, and components such as the RAM have been soldered on. Therefore, you'll need to bump from the default 4GB to 8GB in the build-to-order options at check out in order to future-proof the PC.

Reasons you shouldn't buy a Mac mini: The processor

The 2012 Mac mini came with Ivy Bridge-generation Intel Core processors with quad-core options available, but the new Mac mini's performance peak has been eroded by removing any quad-core processors from the list. It's not that the 2014 Mac mini is a slow machine, but it does seem a shame that Apple has limited it by offering only modest processors.

Reasons you shouldn't buy a Mac mini: The graphics

If you're looking to use the Mac mini to play games, you're likely to be left disappointed. The base model has Intel HD Graphics 5000, which we found could play Batman: Arkham City for OS X at 31 frames per second, but at full-HD resolution the Mac mini struggled at 15fps, too slow for smooth playing. That's even slower than the entry-level 2012 Mac mini, which we found managed 20fps in the same test. Read: Best Mac for gaming

Reasons you shouldn't buy a Mac mini: Monitor not included

Yep, you'll need to buy yourself a monitor, mouse and keyboard (unless you have one already, of course) before you can use the Mac mini. While this means you'll have to cough up some extra cash, it does also mean that you can get yourself a monitor that suits your needs perfectly, rather than the one that Apple supplies you with.

Reasons you shouldn't buy a Mac mini: It doesn't have a disc drive

Ok, so that's not much of a surprise. The non-Retina MacBook Pro is the only Mac left with an optical drive. But still, it's a bit frustrating to know that in addition to your monitor, mouse and keyboard, you'll also need an external disc drive.
