In this guide to the best business computers, we show how modern offices can still benefit from desktop PCs.
While laptops and smartphones are becoming ever more powerful, and allow us to work while travelling, it’s still important to get the best business computers for you and your company’s needs – as there are certain tasks that require the additional power of a traditional PC.
When you work in an office all day, there’s nothing quite like a business desktop PC for getting work done. They’re usually much more comfortable to use than a laptop, and they can easily be maintained and upgraded, so you don’t need to buy a new model every couple years.
The best PCs for business will usually offer a lot more power for a lot less money than the best business laptops, so if you’re looking for an affordable way to populate your office with powerful machines, we fully recommend opting for the best business computers.
We’ve also included our exclusive price comparison tool, which will search the web for the best deals, so once you’ve found the best business computer for your needs, you can buy in confidence knowing you’re getting the best price.

The types of desktop PCs
A recent development in the desktop PC world has been a modest diversification of the system case. The typical business PC comes in a mini-tower box, which is probably best sited under or next to your desk.
But if space is at a premium, a smaller case would be a better choice. Dell, for example, delivers its Optiplex models in mini tower, ‘thin’ desktop and ‘compact’ small form factor sizes, each model offering the same computing power but in a different case.
Three other formats that have grown in popularity are:
 All-in-one, otherwise known as AIO, which combine the monitor with the base unit. The move to power-efficient components, the falling price of LCD panels and the ubiquity of touch functionality make AIO an increasingly popular choice for businesses. The all-in-one PC essentially resembles a slightly larger than normal LCD display that contains the processor, hard drive and memory built-in to the screen casing. The end result is a very elegant, clutter-free desktop PC.
 Ultra-small form factors, otherwise known as net tops or mini PCs, which borrow a lot of their designs (and components) from laptops. They are essentially laptops without a screen, input peripherals and a battery.
 HDMI dongles which have been inspired by tablets and smartphones and often share parts with the latter. These are usually used for display signage or in niche markets. They are usually not powerful enough for most tasks but things are likely to improve by the end of 2016.
