The best business computers still have an important role to play in any modern office, and in this guide, we list the top modern business desktop PCs that money can buy.

Laptops and smartphones are essential business tools, and are becoming more powerful and feature-rich every year, but while they are good for people who travel a lot for work, they cannot compete with the best business computers for certain tasks.

For a start, desktop PCs are much more powerful than the best business laptops, and they are cheaper as well. Also, unless you're buying an all-in-one computer, these business computers are also relatively easy to open up and upgrade, making them far more future-proof than laptops or smartphones, which can sometimes start to feel rather outdated after only a few years.

This makes the best business computers a wise financial decision when kitting out your office. And, while traditional desktop PCs are excellent devices to have in an office, we've also listed some of the best all-in-one PCs as well. These devices, like Apple's iconic iMac, have the computing components built into a screen. While this means they are less easily upgradable than traditional PCs, they are easier to set up, take up less space on a desk, and look fantastic as well. Aesthetics might not be your primary concern when buying a business computer, but they will make almost any office or studio look clean and modern.

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.

Top 10 best business desktop PCs

To help narrow down your search for the ideal system for your business, here are TechRadar Pro's top 10 business desktop PCs.

Desktop PC

1. Dell OptiPlex 3050 Micro

Cheap work PC from Dell

CPU: 7th Generation Intel Core i3-7100T | Graphics: Intel HD Graphics | RAM: 4GB | Storage: 500GB HDD | Connectivity: Gigabit Ethernet | Dimensions (W x D x H): 18.2 x 3.6 x 17.8 cm

Flexible specs
Slim design
Not a powerhouse

Dell is a well-known and well respected name when it comes to business computers, so you can be sure when you buy a machine from Dell that it is a well-built and well-supported device. The Dell OptiPlex 3050 Micro offers very good base specs that can be customised to your needs, for a very compelling price. The slim line case also keeps your desk or office from feeling cluttered.

A formidable upgrade

Even though the iMac 27-inch’s last update was only last year, Apple couldn’t help but step up in the upgrades department with its 2020 follow-up. Specs-wise, this model sports some massive improvements while also upgrading its webcam and microphones for a felicitous update. More people are working from home these days, and this seems like the best all-in-one PC to invest in without being forced to make some considerable space in your existing area. Sure, its overall design hasn’t seen so much as a tweak, making it look a bit tired, but if power is at the top of your list, this one’s the best business PC for you.

Slim and stylish

CPU: Intel Core i5-6500T | Graphics: Intel HD Graphics | RAM: 8GB | Storage: 256GB SSD | Connectivity: Gigabit Ethernet | Dimensions (W x D x H): 16.5 x 3.5 x 16.5 cm

This simple yet powerful device has a small form factor that makes it slot onto desks or in meeting rooms with ease, and with dual-microphones, HP Noise cancellation and specialist conferencing software, it makes it the perfect device for holding meetings on.

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:

[1] 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.

[2] 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.

[3] 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.
