According to Lenovo's website, the machine I received dates from October 2016. However it looks and runs like new. Inside there was a little dust on the fan blades - I would say about a month's worth, so I don't know what this PC was doing for the other 6 years of its life, but not much, that's for sure. Came with a perfectly running image of Win 10 Pro. Kind of unreal to see Windows running fast and smooth actually :-DThe only thing missing (apart from original packaging) was the little kickstand thingy that helps it to stand upright. I took off half a star because the 'Amazon Renewed' category is so vague. It wasn't clear to me if I'd be getting a customer return, distributor surplus or inventory out of a corporate environment. The machine is older than I expected but condition wise it is fine. I just think Amazon could and should be clearer about what exactly I would be getting. And I took off another half because this machine does _NOT_ have WiFi. Not a deal breaker for me but it might be for someone else.PS If I could have gotten the PC only (no kb or mouse) I would have done that. The supplied kb is a wacky gaming one that has a built in light show. I'll probably just give that away.UPDATE: I looked at the SMART data for the SSD and found that it had 6,100 hrs of up-time over 370 power cycles, with 14TB written to the drive and 120 unsafe shutdowns. That all sounds like a lot to me, although it reports as healthy.
