I purchased ten of these because the specs suited my needs - cheap, micro-form factor, fast, SSD, lots of ram. I am pleased to say that each was exactly as advertised, each has wifi built-in, and yes the included keyboard and mouse are cheap, and perfect for our Zoom Room digital signage. Each looks brand new, no scuffs or anything. Clean inside, no dust. These must have sat unused on corporate desks for years during the Covid pandemic. Each has the 4th Gen Intel i5-4590T CPU and Win10 Pro, and with a little TPM bypass script I successfully upgraded for free to Windows 11 Pro. So yeah, I got this 4th gen CPU from 2015 running Windows 11 like a boss. Super speedy, too.Apparently Amazon Renewed simply links to random vendors, because I ordered an additional three units after these 10 because I needed more (don't we all?), but they came from a different vendor named ASTSYS and these were slightly different than the other ten units from the vendor named ReFurbees. To be fair they have wifi and also include a USB bluetooth adapter...and a spare USB wifi adapter for extra measure. And weirdly, their refurb process includes applying a black adhesive sticker over all exterior surfaces to hide possible blemishes. But, essentially the same so I can't complain. These latter three units were $20 less, each about $150 so I feel pretty good over all.
