As well as traditional tower desktop computers, there are also all-in-one computers available. These have all the components built into a screen – the Apple iMac being a great example - and there are a number of advantages to this. First of all, they are stylish and space-saving, as you do not need to have a big box sitting on your desk – just the screen, a mouse, and a keyboard. As the computer is built into the screen, it means you don’t need to buy a monitor separately either, which can save you money.
There are a few downsides you need to consider with all-in-ones, however. All-in-one computers can’t be easily upgraded like traditional PCs, as the components are usually specially designed to be fitted behind the screen – much like a laptop. They can also be more expensive, and you'll have to consider the screen quality as part of your purchase, rather than being able to take your pick from the best monitors for photographers.
