'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
Lenovo keeps things simple with its ThinkCentre M910z all-in-one desktop system. Rather than following rivals such as Apple's iMac Pro or the Dell Precision 5720 into high-end graphics and design work, the M910z simply aims to provide a good all-round office PC at a competitive price.
It makes absolutely no attempt to compete with the elegant, slimline design of its rivals, either. This is a distinctly old-school business PC, with a chunky black border running around the edges of the screen, and a big, heavy pedestal stand that you have to attach yourself when you unpack the unit. The M910z only has a 23.8-inch screen (diagonally), but the entire unit measures 23-inches wide -- that's only one inch less than Dell's Precision 5720 with its larger 27-inch display. It even has old-fashioned physical buttons on the right-hand edge for features such as the brightness controls or muting the internal microphone.
But what it lacks in elegance, the M910z makes up for in functionality. You're unlikely to need a 4K or 5K display for running business apps such as Microsoft Office, so the 23.8-inch display contents itself with just standard HD resolution (1,920x1,080 pixels, 92.5dpi). However, the display still provides good image quality and is well suited to creating presentations and business graphics, as well as more straightforward productivity software.
Lenovo pays good attention to detail too, with a non-gloss finish on the display that helps to reduce glare and reflection from overhead office lighting, while the 'ultraflex' stand allows you to quickly adjust the height and tilt of the screen. Lenovo's wired keyboard feels good and sturdy too, and is more than capable of coping with some heavy-duty typing or number crunching when you're on a deadline.
We also like the physical switch for the shutter that blocks the built-in camera, which could be handy if you use Skype for video calls in the office. And, for additional security, there's also a 'Smart USB Protection' feature to prevent data being transferred onto external USB storage devices, while still allowing you to use other USB peripherals such as the mouse and keyboard.
Connectivity is good too, with two USB 3.0 ports and a memory card slot on the left-hand edge of the unit for easy access. There are four more USB ports on the back of the unit, along with Ethernet and DisplayPort connectors; there's even a build-to-order option that lets you add an internal DVD drive if you want one.
Although Lenovo refers to the M910z as an 'enterprise-ready' system, it does sell one entry-level model that runs Windows 10 Home and includes a non-touch screen for just £930.79 inc. VAT (£775.66 ex. VAT, or $899). However, business users who need Windows 10 Pro will have to step up to the alternative touch-screen model tested here. This model costs £1,059.99 inc. VAT (£883.33 ex. VAT, or $1,187.10) with a quad-core Core i5-7500 running at 3.4GHz (up to 3.8GHz with TurboBoost), along with 8GB of RAM and a 256GB SSD. Lenovo's website also provides a wide range of build-to-order upgrades, including faster processors, or less expensive memory and storage options. You can even choose a variant without the internal camera if you're concerned about privacy and security in the office. The one omission here is the option to upgrade the integrated graphics to a discrete GPU -- although that's hardly essential for a general-purpose office PC such as this.
And, in that role, the M910z excels, achieving a score of 4,380 when running the single-core Geekbench 4.1 processor test, and 11,250 for multi-core performance. Those scores ensure that the M910z will provide strong performance for business productivity software while still maintaining a very competitive price. The solid-state drive performs well too, with write and read scores of 1,535MB/s and 2,264MB/s in the ATTO disk benchmark. And even without a discrete GPU, the M910z manages 42fps when running the Cinebench R15 OpenGL benchmark, which will certainly allow it to handle basic photo- or video-editing for business presentations.
Included in the price is a three-year on-site warranty, and Lenovo's manual also provides detailed instructions on how to dismantle the entire unit in case you need to perform your own repairs or upgrades.
The ThinkCentre M910z might not have the sleek design or the high-end performance of some of its AIO rivals, but it's a thoroughly capable office PC that provides strong performance for a variety of tasks at a highly competitive price. And, with Lenovo's three-year warranty and easy repairs and upgrades, you can be sure that it will earn its keep for years to come.
