I got almost the exact same model # over at Lenovo's web site. I got the B540 25681RU and this one is the B540 2568"2"RU. Big difference is on their site you get a 2TB hard drive and 8 gb of memory!! Also, you get a 1gb nvdia video card. I also paid $879 for it. I love this thing. It's a bit big at first but you get used to it. It's nice to just reach up and use your hands as if on a smart phone or tablet. ( like using your fingers to zoom in and out of a picture. The build quality is wonderful. It has a nice sleek look to it. The processor is nice and quiet too. There is one cord to plug in to the wall and thats it! I believe it's 1080p also too. Nice high resolution screen. Sorry I don't do gaming so I couln't tell you about that. The youtube videos are fine and load quickly. It comes with a high quality near full size keyboard with nice keys that have a quality feel to them. However the mouse is horrible. I replaced mine with a $20 Logitech mouse. It also has HdMI out. The sound is actually pretty good for an all in one. It's nice not being stuck in a little laptop yet I can move this thing on a dime around the house. It's got better specs than most towers too with all their connections and wires.. It is a bit heavy though, but, I like that . It seems to have a quality build to it as a result.

Verified Purchase
I mainly purchased this product for the huge discoune Amazon had at the time I purchased it. This is an average Pc with great Display. Product finish is Excellent. Only one thing is not great about it which has something to do with Amazon. they display the product with TV Tuner and IN/OUT HDMI inputs but the product I recieved only has HDMI OUT PUT and no TV tuner. Last but not least Price was very tempting and that is why I made a disision to buy this PC. very helpfull product review for this PC is available on PCMAGAZINE.COM

I bought this computer a couple of months back and LOVED it! I especially loved the kids games on it and the thick glass. Just because it's gorilla glass does NOT mean that a gorilla couldn't break 3 year old did while I was making dinner and letting her play games on it. I turn my back for one second and "Crack"! Apparently she thought that the hole punch might make her games more interesting. The sad thing is that it did not effect the display at least for 1 week. The mouse worked fine, so... I used that instead of the touch screen, and the crack was in the side and on the black portion, so it did not even hamper the display for quite awhile. Problem is, Windows 8 (geniuses that they are) integrated the touch screen in with the display drivers... So if the touchscreen goes, so does your display and so does your WHOLE all in one computer unless you want to deal with the Lenovo repairs people.

Now... I didn't really think this whole all in one thing through. The monitor is built IN with the computer. We've had to replace bad lcds before... Not a big issue... $200 tops. They want to charge $100 just to look at it (That does not include the shipping back.. which I'm sure will be high) and will not give me a price estimate on what it will cost to replace the lcd and gorilla glass until they get it. I'm pretty sure that the display, lcd, camera, etc.. are fused in with the case, so it might be pretty high, and after it's all said and done, it might cost more than the $650 that we spent on the computer. Not to mention, from other reviews, I heard that they take their time on them and are difficult to deal with (the latter I can concur with). If I knew how much it would cost to repair, and if it is too high, I would like the option to throw this thing in the junk heap and buy a regular old, parts easily replaceable desktop computer like I SHOULD HAVE in the first place.

A warning to all who are thinking to buy Lenovo Products. They do NOT repair their products in a timely manner and their repair service, once engaged, is very, very difficult to contact. A model similar to this one was sent to their repair depot in Texas over 3 weeks ago and there has been no communication about it's repair status.

Attempts to call various contact numbers end up with dropped lines or, in one case, a wrong number that is on the service label send out by the company for the return of the computer.

It takes a maximum of 2 hours to replace every component in a computer. Most techs can do it in less than an hour, yet this one remains unrepaired for nearly a month.

AVOID Lenovo products.
