Power, Heat, Noise
The Edge 91z does a decent job controlling its energy output. When compared to other all-in-ones, it’s on par — meaning, the system will take just about the same amount of power. On boot-up the Edge 91z started around 25 watts and that number grew to 49W, and then maxed out at around 64W. While sitting idle it drew the same exact wattage as the HP 100B all-in-one at an even 35W. When we exerted the system and ran a CPU and graphics benchmark at the same time, it stayed between 55 and 58 watts.

The Edge 91z also does a great job of controlling its heat and noise. It has a large system fan and a microprocessor fan. There is a very large exhaust vent at the near top of the display, which allows for a lot of the heat to escape through very efficiently. Even when exerted, the Edge 91z makes barely any noise.

Software and Security Features
The Edge 91z comes with many Lenovo-based security and utility apps for free. They include Lenovo Rescue and Recovery, Password Manager, Communication Utility 2.0, Lenovo AutoLock 1.0, View Management Utility 2.1, Desktop Power Manager 1.0, Lenovo ThinkVantage Toolbox V1.5, Lenovo Thinkvantage Tools 3.1, ThinkVantage System Update 4.0, and Lenovo Message Center Plus. It also comes pre-loaded with Norton Internet Security (2011). The system comes with pre-loaded “bloatware” (software most users wouldn’t utilize) such as the Bing Bar program. A full list of pre-loaded applications are listed below.

Keyboard and Mouse
The black wired USB keyboard and mouse are both very standard and business-oriented. They keyboard is nothing special, but at the same time typos should be at a minimum. It’s a “Chiclet” style full-sized keyboard with extra spacing between the keys. The mouse has two separate buttons and a red scroll wheel/third button. It’s comfortable to use, but the buttons make a lot of noise when pressed.

We would recommend the Lenovo ThinkCentre Edge 91z to anyone who needs a new business PC (or anyone who wants an all-in-one in general). Lenovo was able to fit good hardware, a decent build, and a big and beautiful full HD (1080p) display into an all-in-one for under $1000. Some resellers are even selling the 91z with the specs in our review unit for around $700.

While using the Edge 91z, we noticed that it would be easy to forget that you’re working on your office PC instead of your home computer. What office PC has such a dazzling 21.5-inch display with edge-to-edge glossy glass and such a stylish design?

Lenovo ThinkCentre Edge 91zThe combination of the core specifications in our review unit worked well together. The Intel Core i5-2400S quad-core CPU, 4GB-1333 RAM, and Intel HD graphics were able to multi-task office productivity apps and then some with a breeze, despite that the processor in the system doesn’t have hyperthreading. Fullscreen FHD (1080p) video also looked great. Another great feature was that it ran completely silent even when exerted, a detail we don’t want to just overlook. A silent machine is very important–nobody wants to hear a constant distracting buzzing noise while working.  

The biggest problem we had with the Edge 91z is its glossiness. The edge-to-edge glass on the display is so glossy it almost seemed like we were looking in a colorless mirror at times. The ultra-reflective glass will be even worse in a well-lit office room. Although, the high gloss will most certainly help the display show off its brilliant contrast. All of the gloss in and around the system also allowed for it to collect dust, fingerprints and grime easily. Definitely have a microfiber cloth handy so you can clean it off a few times a week. We also found it annoying that there weren’t enough USB ports on the side (there were only two). The rest of the USB ports are located on the lower-back of the system.

If you’re considering purchasing the 91z, you will have to buy through a reseller such as Best Buy or Office Depot, or any number of resellers selling online. (Meaning, you can’t buy it directly through Lenovo). Shop around for the system with the specifications and price point that are right for you and your business.
