ThinkCentre Edge 91z : With Intel Core i3 or i7 offers powerful performance for the money. it conceals its powerful components beneath a modest-looking chassis
Although is not as sleek, silvery elegance of Apple’s iMac, but Lenovo’s ThinkCentre Edge 91z is a far more affordable option for people who want a compact all-in-one desktop computer.
With the black plastic design of the ThinkCentre is fairly nondescript, but Lenovo does have a more stylish range of IdeaCentre all-in-ones that are designed for home use. The ThinkCentre range is primarily aimed at business folk who just want a tidy PC for running basic office apps
Display & Design
Lenovo has revealed that its new 21.46 x 16.31 x 3.18-inch (545.2 x 414.3 x 81 mm), 21.5in widescreen display, with a 1920 x 1080 resolution which is pretty good, futhermore the display is glossy. Although it might seeme a bit dark when initially set up, but a quick press of the Brightness button on the bottom-right edge of the unit revealed that the intensity was only set at 50 per cent – bumping it up delivered a clear and sharp image. However, a less glossy and reflective screen coating might be a better choice – especially if you’ve got harsh strip-lighting in your office.
Engine Room, Memory & Storage
The Edge 91z is equipped with an Intel dual-core i3 or i7 processor which running at 3.1GHz, along with 2GB of Ram and 320GB hard disk. It is fairly modest spec these days, but a 3.1GHz processor is more than adequate for a workaday business PC that simply needs to run Microsoft Office, surf the web and handle email.
Connectivity
The PC comes with small built-in speakers produced a predictably thin sound, but there’s an audio output connector so that you can connect external speakers for presentations or simply listening to some music while you work.
Lenovo includes both wired and wireless mice with the ThinkCentre, but its UltraSlim wireless keyboard feels rather flimsy. I’d prefer something a bit sturdier when I’m thumping away on deadline day. But, keyboard aside, the ThinkCentre proved to be a fairly reliable workhorse PC.
There are VGA and HDMI ports for connecting to external displays, and audio input and output available for external speakers and microphone. The Edge 91z doesn’t have built-in Bluetooth, but with wireless peripherals bundled with the PC, that won't inconvenience many, if any, buyers.
Graphic details
With 4GB of Ram is good enoughy for people who like to do mult-tasking and opening few application at once. This base model clocked up an overall score on PCMark 7 of 2227, a fairly unspectacular figure that falls in line with expectations for this configuration. However Lenovo is a bit vague about the graphics chip as is only referring to it as the 'intel HD Family'.The device relies on the integrated Intel HD 2000 core built into its Core i3 Sandy Bridge CPU.
