Lenovo ThinkCentre M720s 2018, Core i7-8700, 16GB, 1TB SSD, Black

A refurbished office workhorse with a 6-core i7 and 1TB SSD for under $500. Great for spreadsheets, terrible for games.

The i7-8700 still holds up surprisingly well for everyday work. Six cores and twelve threads chew through spreadsheets, browser tabs, and multitasking without breaking a sweat. The 1TB SSD is the real star here, making boot times and app launches feel snappy. But the integrated GPU sits in the bottom half of our database, so don't expect anything beyond basic display output. It's fine for office work and video streaming, but it's a dead end for anything 3D.

Against the Dell Tower Desktop ECT1250 and HP OmniDesk M02-0234, the M720s holds its own on CPU and storage, but those competitors often ship with newer processors and better connectivity. The Apple Mac mini M4 absolutely destroys this thing in performance and efficiency, but it costs significantly more and locks you into macOS. The Minisforum UM760 Slim and GMKtec Nucbox K8 Plus are the real threats, offering newer Ryzen chips with much better integrated graphics in even smaller packages for similar money. If you need Windows and raw CPU threads on a budget, the M720s is fine. If you want modern efficiency or any GPU headroom, look at the mini PC crowd.

At USD 397 to USD 455 across two US listings, this is a solid deal for a capable office desktop. The spread between vendors is real, so shop around. The lower end of that range makes this a no-brainer for basic productivity. The higher end starts to feel less exciting when newer mini PCs with better integrated graphics are creeping into the same price bracket. But for pure office work, this is a lot of computer for the money.

The Lenovo ThinkCentre M720s is a refurbished workhorse that knows exactly what it is, and doesn't pretend otherwise. You're getting a 6-core i7-8700, 16GB of DDR4, and a full 1TB SSD in a compact SFF case for under $500. That's a lot of practical office muscle for the money. The one thing to know? This is a productivity machine, not a gaming rig, and the integrated Intel UHD 630 graphics will remind you of that every time you try to do anything graphically demanding.

If you're looking for any kind of gaming performance, this isn't it. Go get a mini PC with a Ryzen 7000 or 8000 series chip, like the Minisforum UM760 Slim, which has far better integrated graphics for similar money. And if you want a silent, efficient desktop that sips power, the Apple Mac mini M4 is in a completely different league, just be ready to pay for it.

The Lenovo ThinkCentre M720s is a straightforward recommendation for anyone who needs a reliable, compact Windows desktop for office work, web browsing, and light multitasking. The i7-8700 and 1TB SSD deliver where it counts for productivity, and the refurbished price is genuinely attractive. Just don't buy it expecting to play games or do any serious graphics work. For pure office duty, this is a smart buy.
