Lenovo ThinkCentre Lenovo ThinkCentre M70s Gen 5 Desktop Computer Review

The Lenovo ThinkCentre M70s Gen 5 is a capable but boring office PC. It's fast enough for daily tasks and comes in a tiny, quiet box. Its integrated graphics and limited power supply make it a dead end for anything fun. Only consider it for basic business deployments.

The Lenovo ThinkCentre M70s Gen 5 is a small form factor desktop built for the office, not the arena. It's got a solid 14th Gen Intel Core i5 and 16GB of DDR5 RAM, which is more than enough for spreadsheets, emails, and web browsing. It's quiet, reliable, and comes with Windows 11 Pro out of the box.

Just don't ask it to do anything fancy. The integrated Intel UHD Graphics 730 means gaming is a non-starter, and the 260W power supply locks you into this basic configuration. This is a workhorse, plain and simple.

For general office work, the M70s is perfectly capable. The i5-14400 is a decent mid-range CPU, landing right at the 50th percentile in our database. It'll handle multitasking between a dozen Chrome tabs and a few Office apps without breaking a sweat. The 16GB of DDR5 RAM is also a good starting point. The big bottleneck is the graphics. That integrated GPU sits in the 24th percentile, so even light photo editing will feel sluggish. The 512GB SSD is fine for the OS and core apps, but you'll want to add more storage pretty quickly.

At around $850 to $900, the value proposition is shaky. You're paying a premium for the small form factor and the business-oriented features like the Q670 chipset and Windows 11 Pro. For the same money, you could get a consumer desktop with a dedicated GPU and more upgrade headroom. It's only worth the price if your absolute top priorities are a tiny, reliable box for basic office tasks.

Don't confuse this with the gaming desktops listed as competitors, like the HP Omen or Alienware Aurora. Those are in a different universe for performance. A more apt comparison is against other business SFF PCs, like Dell's OptiPlex series. The M70s holds its own there, with its DDR5 RAM being a slight edge. But if you're a home user, a mini PC or even a modern laptop might offer similar performance in a smaller package for less money.

Skip this if you have even a passing interest in gaming, content creation, or future upgrades. The integrated graphics and tiny power supply make it a brick wall for performance. Also, if you need lots of local storage for media or projects, the 512GB SSD will feel cramped on day one.

Buy this if you're an IT manager deploying reliable, locked-down workstations for a standard office environment. It's a set-it-and-forget-it machine. For a home office user who might dabble in anything beyond web apps, or for anyone who thinks they might want to add a graphics card later, you should look elsewhere immediately.
