# ThinkCentre Edge

The ThinkCentre Edge is a series of desktop computers from Lenovo, designed primarily for home offices and small businesses. The product series features desktops in both tower and All-in-One form factors, designed to save up to 70% desk space as compared to traditional tower desktop PCs.
The ThinkCentre Edge desktop series represents the first time the 'Edge' brand has been used for any Lenovo product outside of the ThinkPad product line. The first desktop in the series was the Edge 91z AIO, announced on May 16, 2011.

## Design

According to Paul Scaini, the Segment Manager for the ThinkCentre product line, the ThinkCentre Edge desktops were the result of a large amount of time spent on refining the overall product appearance. The Edge 91z was described in the article as being the epitome of that effort, with its Infinity Glass design.
Scaini wrote that the Edge AIO desktops had the same serviceability and mounting features as the ThinkCentre M Series AIOs. They used second-generation Intel Core i desktop CPUs and Lenovo Enhanced Experience 2.0.

### ThinkCentre Edge 91z

The ThinkCentre Edge 91z AIO was summarized by PCMag as being a reasonably priced, powerful desktop with the capacity to "give the iMac a run for its place in a design studio." The Edge 91z was 2.5 inches thick, and was described as being "less flashy" than the IdeaCentre desktops and AIOs.
The Edge 91z was described as being simple with a seamless front and two removable feet that could be detached from the AIO. The space between the two feet was open and meant to store a keyboard. This was described as being different from the IdeaCentre B520 desktop, in which the keyboard storage was blocked by the speaker bar.
The display on offer with the Edge 91z AIO was a true 1080p HD. A drawback of the screen was the reflective glass front panel.
An optional DVD writer was available on the Edge 91z AIO. The AIO was reported by PCMag to be lacking in "would be nice features" such as eSATA ports, USB 3.0 ports, and HDMI-in.
The software on the Edge 91z AIO was reported to be a useful set, with the system free of unnecessary software. Software preinstalled on the AIO included Lenovo Rescue and Recovery and utilities for the DVD burner and the web camera.
In comparison with the Apple iMac 21.5 inch (Thunderbolt) the ThinkCentre Edge 91z was reported to be similar in terms of performance and specifications. The iMac was described as being slightly faster on 3D-related and everyday tasks, while the ThinkCentre Edge 91z was slightly faster on multimedia benchmarks. Both desktops contained similarly sized widescreens, AMD graphics, Intel Core processors, 1 TB storage space, and could be used as external monitors for laptops.
