Consumer review (

Solid performance for the price.


I paid $679 for this PC and at the time I would confidently say you won't find a better deal for this price.

This PC was the best prebuilt I could find under $700 for gaming ( unless you're willing to gamble on IBUYPOWER or CYBERPOWER). I've had it a few weeks now and it's been performing great so far. It's fast and powerful for the price and the gtx 650 is...

The mini-hdmi port on the video card is awkward most adapters won't fit so you'll need an actual mini-hdmi cable if you plan on using it instead of DVI. The PSU is pretty wimpy I'm already looking at replacing it just so I can add an SSD because it...

Great computer but Lenovo bad


I live in NC about 5 miles from their North American Headquarters. I bought the desktop and laptop to support the company and my neighbors who work there. THAT WAS A MISTAKE!!!!! I've added a SSD and 4gb of ram and the machine boots in 15 seconds. At...

Boots fast as long as you don't have an external hard drive connected

Boot hangs when you have an external hard drive connected

At This Price There is No Peer


Whether you spend $300 or $1000 you won't go wrong buying Lenovo.

At this price there is no peer.......this thing screams ; I built a couple computers for myself as buying boxes off the shelf with good hardware was either nearly impossible or required mortaging something ; Then I bought a Lenovo and it immediately...

If there are any negatives I haven't experienced them

In the year and a half that I have owned this computer the hard drive has failed 3 times. Twice the one key recovery has been the only option. This time I cannot even get to that point. Lenovo customer service is horrible.

Looks Great But Deceiving


Purchased a month ago. Had windows 10, Edge, and Internet Explorer 11. Setup was simple! No matter what I do, often fails to load pictures on websites or fails to load website when I type url into address bar. Called Lenovo Tech Support. Worst support...

Buy it while it's still available.


This is an amazing machine. I am so impressed buy the craftsmanship and the quality of the tower. I have had it for couple of months now and even after upgrading to Windows 10, it still performs the same as the day I got it. from the time that I press...

Dual Monitor watchout


This is a good computer except it does not work for dual monitors although it has the ports. This is a total disappointment since I am just getting around and excited to finally connect my second monitor to make life easier. Good fast system just wish...

Not quite for Gaming but still a good one


Great for basic games like LoL or DOTA II. Great for video/audio editing at the price point. Large hard drive. Only complaint is if you don't use opticle audio out the headphone jack has tons of feedback

Great machine for photoshop


I am a graphic designer/art director by day and I work at home in the evenings doing personal projects. This works great for what I have to do. It has a decent graphics card for moving pixels and decent RAM .
