Lenovo ThinkCentre M91p: Business-Class Desktop PC Lacks Frills


If you love the old-school look of Lenovo ThinkPads, but you want desktop performance and pricing, check out Lenovo's ThinkCentre M91p series. This machine packs second-generation Intel processors into a slim, retro-style case.

Plenty of USB ports

Poor performance, for the price

It has the look of an old-school ThinkPad, but you can get similar performance and better specs at a lower price.

Lenovo ThinkCentre M91p


The system has a decent amount of internal room for a USFF PC. The top of the case pops open by pushing a blue tab on the back panel, and the whole chassis opens clamshell-style to present the system's compact motherboard. It has full-size optical and...

Compact form factor. High build quality. Includes PCI card slot, DisplayPort jack. Easily serviced

No HDMI, eSATA, USB 3.0 ports. Only one-year warranty included. Uses external power supply

The Lenovo ThinkCentre M91p defines the enterprise-class desktop, with an easy-to-service yet sturdy chassis. Its Intel Core i5 processor will satisfy your workers for a while.

Lenovo ThinkCentre M91p 0266 (B8U) Ultrasmall Desktop


Not so long ago, if you wanted a compact business PC, you'd have to dial down your performance expectations and pay several hundred dollars extra for the convenience of saving a few inches of office space. But the Lenovo ThinkCentre M91p 0266 (B8U)...

Compact design ; Full-size hard drive and optical drive increase upgrade potential ; Supports Intel vPro technology

Limited expansion options ; Potential warranty confusion

An innovate design, full-size drives, built-in security, and remote management features make the M91p Ultrasmall compact business PC a good choice for space-strapped work groups.

ThinkCentre desktop comes in a nice little package


The Lab looks at the ThinkCentre M91p, an Ultra-Slim Formfactor desktop computer to see how this type of computer holds up.

Good internal space management; good speed

Not much room for upgrades; integrated graphics performance is low

Lenovo ThinkCentre M91p review


The Lenovo ThinkCentre M91p is a slim, small-form factor PC for the office.

The Lenovo ThinkCentre M91p is a solid performer at a reasonable price. It lacks a Blu-ray disc drive and integrated Wi-Fi, but shop around online and you may grab a bargain.

I thought I'd try this rig out and was pretty disappointed... The lack of space is one thing but the hum really pushed me over the edge... ultimately after getting every installed and transferred over to it, I tried to burn a CD and the DVDRW was...

Fast machine at a cheap price

Compact ; No room for upgrades ; DVD Writer installed is from the year 2006 and didn't work from the start ; 750GB HDD turns into 690GB... Where did the rest of the space go

Not too sure after 30 days


I like these, and have 3, but this one machine is being problematic.

Clean install of Win7Pro, machine boots fine, runs pretty fast

Questioning the DVD players, which seem not to read some MSOffice DVD's and want to format blank DVD's, stopping with "Format not successful" when making backup system discs

Response to previous review


Almost all the ThinkCentre's are Dual-monitor capable. You have to use the "Display-port" and VGA together. Just purchase a Display-port to DVI (or VGA) Adapter and you are set for two monitors.

We have mutiple ThinkCentre's in our office. Mostly the SSF. Lenovo is all we purchase now. HP's are horrible (too many motherboard replacements) ; These Lenovo's are Fast, Quiet, Never have trouble, and come with a 3 year On-site warranty. Lenovo's...

Lenovo ThinkCentre M91p 4480 - Core i5 2400 3.1 GHz - Monitor : none.


Bought one as a server for the house. Solid build, solid performance, decent price, and the rigid case was great for some Dremel induced drive array mods. :)
