I ordered this because I was needing a Ubuntu box for daily desktop work, and didn't feel like either buying a no-name mini PC, or spending a lot more cash for a new machine.  Yes, it is refurbished, but it does the job, and has very similar benchmarks as a recent generation Celeron.It came with a wireless dongle, which worked without issue.  It also came preinstalled with Windows 10 Pro, which I made sure activated, then reinstalled it, to make sure the activation "stuck".  After that, I erased the SSD, and installed Ubuntu on it.The SSD was a SATA model, which is fine for my needs.  The M.2 slot I may use in the future for additional storage.Even though it has been out of warranty for a while, HP still had recent firmware updates for it, which installed without issue.  I installed them under Windows, because that is the easiest method before I reinstalled the OS.Overall?  This was intended for a business class desktop.  It has TPM functionality, remote access functionality... all the things that are needed for an IT department.  Definitely worth the money for what I'm using it for.  Can it run Crysis at the highest resolution?  Nope.  However, for daily mail/web, and stuff like Vagrant, it does the job quite well.Performs as advertised, definitely five stars.
