I've ordered 8 of these over the past 4 moths to use as workstations at my business.All of them have arrived clean and fully functional. All USB and Displayport/VGA ports working perfectly.The only downside is that some of them come with VERY CHEAP SSD drives. Some of the sellers put in a name brand used drive, but others put in bottom of the barrel m.2 or SATA drives that don't have any branding on them at all. If you get a non-branded one, i highly recommend you replace it. The one machine i didn't replace the drive of stopped booting after about 3 weeks of use because the SSD died.Get yourself a Crucial 250 GB SATA or m.2 ssd and save yourself the headache of loosing yoru data a few months down the road.For the price, it's still a killer deal. Even if i have to add an extra $30-40 for an SSD.
