Summary: The ThinkCentre M92z is a
good-quality business-grade 23in. all-in-one computer. To get the most
out of it, though, you may need a better-specified model than the
entry-level system reviewed here.
Lenovo's ThinkCentre M92z All-In-One Desktop is a business-class stablemate of the hybrid SME/consumer ThinkCentre Edge 92z
that we examined recently. Built around a 23in. screen, the ThinkCentre
M92z can be configured with a full set of security and manageability
features: our relatively low-end review unit was missing a few options,
though, including a vPro-compliant processor and the touch-screen that
could render the system fully Windows 8-ready.
Design :
The ThinkCentre M92z is a matte-black system with a PC's innards built onto the back of its 23in. screen. It conforms to the standard layout, with a selection of easily accessible ports on the left, an optical drive on the right and further ports at the back.
Our review unit came with a height-adjustable stand that allows for
plenty of tilt and swivel, so you should be able to arrange the screen
at a comfortable angle whether you're sitting at a desk or using the
system in kiosk mode.

The screen itself is a matte-finish IPS unit with a resolution of
1,920 by 1,080 pixels. It sits, slightly recessed, within a 3cm bezel —
with an extra 4.5cm at the bottom for the stereo speakers and monitor
controls. Viewing angles are good, and there's plenty of brightness at
the 100 percent setting. We had the regular screen, but a touchscreen
option is also available, which will be of more interest to anyone
planning to run Microsoft's imminent Windows 8 OS.
The ThinkCentre M92z is no designer system, but it looks smart enough
in an understated way — apart from the outbreak of no fewer than six
(wonkily applied) vendor stickers on the bottom right-hand corner:
Our review unit came with an old-school, clacky USB keyboard and a wired USB mouse. Wireless options are available.
Features :
The ThinkCentre M92z that we were sent for review was powered by a low-end second-generation Intel Core i3-2120 processor running at 3.3GHz. This is not vPro-enabled, which may rule this particular model out for many businesses. However, third-generation Core i3/i5/i7 CPUs with vPro are also available. For memory our system had 4GB of 1600MHz DDR3 RAM, expandable to a maximum of 16GB. Graphics are handled by the integrated HD Graphics 2000 GPU (a discrete AMD Radeon HD7650 GPU is also available) and the OS is Windows 7 Professional 64-bit.

Storage comes in the form of a 500GB Seagate SATA III (6Gbps) hard
drive spinning at 7,200rpm; HD options go to 1TB, while SSDs are
available in 128GB and 64GB capacities — the latter as an mSATA card.
Wireless connectivity is catered for by an Intel Centrino Wireless-N 2230
module, which supports single-band (2.4GHz) 802.11b/g/n Wi-Fi and
Bluetooth 4.0. Wired Gigabit Ethernet networking is supported too,
naturally.
There's a decent set of ports and slots dotted around the system. On
the left is a pair of USB 3.0 ports, audio in and out jacks and a card
reader for SD-compatible media. The right-hand side has a tray-loading
optical drive, while the back has the power input, an Ethernet (RJ-45)
port, DisplayPort in and out, and four USB 2.0 ports. The DisplayPort
connectors allow the 23in. screen to be used as a regular monitor, or a
second screen to be attached.
Lenovo makes much of the ThinkCentre M92z's suitability for
communication and collaboration — one of the aforementioned stickers
proclaims the M92z's Microsoft Lync certification, for example. In the
middle of the top bezel is an HD webcam with a sliding cover so you can
ensure it's not going to operate when you don't want it to, a dual-array
microphone helps optimise audio quality, and there's a convenient pair
of volume (up/down) controls on the right hand side of the screen. We
made video calls with the bundled Skype application, and can confirm
that the camera, mic and speakers all perform very well.
Performance & power consumption :
The Windows Experience Index (WEI) for the ThinkCentre M92z is a moderate 4.6 (out of 7.9), the WEI corresponding to the lowest component score. As usual, this is for the integrated graphics — specifically Graphics (Desktop performance for Windows Aero). Memory (RAM) (Memory operations per second) and Primary hard disk (Disk data transfer rate) both scored 5.9, Gaming graphics (3D business and gaming graphics) registered 5.8 and Processor (Calculations per second) led the field with 6.6:

This isn't stellar performance by any means, particularly on the
graphics front. However, there are plenty of options available for
boosting speed if necessary: upgrading the RAM to 8GB or beyond;
specifying a faster CPU; specifying discrete rather than integrated
graphics; and/or fitting an SSD rather than a conventional hard drive.
All of these upgrades will boost the cost, of course.
Running the demanding Cinebench 11.5
CPU and GPU benchmarks shows that the Core i3/HD Graphics 2000/4GB
ThinkCentre M92z lags behind Dell's Core i5/HD Graphics 4000/8GB
OptiPlex 9010, as you'd expect. Note, though, that Lenovo's AIO is some
£400 (ex. VAT) cheaper than the Dell unit we reviewed.
When it comes to disk performance, the ThinkCentre's 500GB SATA III
7,200rpm Seagate hard drive is quicker than the Dell's, using the ATTO Disk Benchmark (129MB/s write and 130.3MB/s read versus 106.3MB/s write and 115.7MB/s read respectively):
The ThinkCentre M92z is pretty power-frugal for a 23in. system, its
lower spec combining to deliver similar power draw (41.6W-67.5W) to
Dell's 21.5in. OptiPlex 9010 (37.4W-71.1W) when running various
workloads:
Lenovo's AIO system is also admirably quiet in operation, even when running demanding workloads.
Conclusion :
The ThinkCentre M92z is a good-quality business-grade 23in. all-in-one computer that's particularly well suited to video communication. To get the most out of it, though, you may need a better-specified model than the entry-level system reviewed here.
