This purchase felt like a gamble after reading some of the negative reviews.  I am happy to say that it is one that paid off for me.The unit looks super clean and came with a new hard drive only 136 hours on it.  The OS loaded just fine and Windows 10 Pro activated without any issues. The CPU, RAM and HardDrive is exactly what’s advertised.  The unit came with a WiFi dongle (that made me smile), and it connect to my network with out issues.I bought this unit with the intention of installing Proxmox and use the machine as a virtual server for my Home Assistant.  Since playing games on it is not the intention, I really cannot say how well it does on that level.  However, you can add a low profile graphic card in it and I’m sure it’ll put out a decent FPS on lower-mid game settings.  Gamers should look to newer hardware since this machine is 2012 technology.The only issue I had was trying to get Proxmox to run correctly.  I had swapped out the HardDrive for a 120G SSD and installed Proxmox.  Everything install fine and loaded up accordingly, but, i couldn’t get the thing to load up my virtual machine I created.  Turns out I needed to change a setting in the BIOS.  That was a challenge since the normal splash screen for the BIOS was removed and I didn’t know what key to press to get into it before it was load Windows or Proxmox.  After a brief research, turns out HP uses F10 and I was able to get into the BIOS and change the setting.  Proxmox works fine now and the VM loads as it should.  So far, so good!
