MINISFORUM UM870 Slim Mini PC vs Lenovo ThinkCentre Neo Ultra Gen 2

The UM870 Slim is the smaller, quieter machine and the better pick for most people who want a fast everyday desktop with strong integrated graphics. The ThinkCentre Neo Ultra Gen 2 is a bigger, heavier box that adds a discrete RTX 5060, 64GB of RAM, 2TB of storage and Windows 11 Pro, so it wins on raw power and out-of-box readiness. Owners of Minisforum mini PCs praise the compact size and port selection but note the barebones feel and driver quirks; ThinkCentre buyers value the warranty and business support.

  • Choose the MINISFORUM UM870 Slim if you want a tiny, quiet desktop for office work, media and light gaming, and you are fine adding your own Windows license.
  • Choose the Lenovo ThinkCentre Neo Ultra Gen 2 if you need discrete RTX 5060 graphics, 64GB of RAM and Windows 11 Pro preinstalled for creative work or gaming.

What reviewers say

Lenovo ThinkCentre Neo Ultra Gen 2

Owners of Lenovo's compact ThinkCentre line generally praise the build, quiet fans and tool-less access, and the Neo Ultra's high RAM and dedicated GPU draw positive notes for creative work. Criticism centers on limited upgradability and fan noise under heavy sustained loads.

What people mention
  • NoiseMixedQuiet in everyday use, but owners report the fans ramping up during sustained heavy loads.
  • UpgradabilityCriticisedThe compact case leaves little room to add cards or swap major parts later.
  • BuildPraisedOwners describe the chassis as sturdy and well finished for an office machine.
  • PerformancePraisedThe high RAM count and Core Ultra 7 are noted for smooth multitasking and creative apps.

Questions and answers

Which is better for gaming?
The ThinkCentre Neo Ultra Gen 2. Its RTX 5060 is a discrete GPU and runs modern games far better than the Radeon 780M integrated graphics in the UM870 Slim.
Which is better for office and everyday use?
The UM870 Slim. It is smaller, quieter and has plenty of CPU and RAM for documents, browsing and video calls.
Do I need to buy Windows for the Minisforum?
Yes. The UM870 Slim ships without a Windows license, so budget for one. The Lenovo comes with Windows 11 Pro preinstalled.
Which is easier to upgrade?
Both allow RAM and SSD upgrades. The UM870 Slim has two SODIMM slots and two M.2 slots, so it scales to 96GB and 4TB. The Lenovo starts higher but has less headroom.
Which lasts longer?
Both should last years. The Lenovo carries a business warranty and support network; Minisforum relies on a smaller support operation, so check warranty terms before buying.
Is the Lenovo worth stepping up to?
If you game, edit video or run GPU workloads, yes. For browsing, office work and media, the UM870 Slim covers it in a smaller, quieter package.
