This is a nice systems. Descent cpu, 8 gb of ram, new genetic mouse and keyboard.  Clean inside, so it was cleaned.  Two pci express slots, one pci slot and one expressx1 slot.  Room for a second hard drive, although unless they are hidden in the case some where, you'll have found mounting the drive without the hard drive screws.Power supply is small, low wattage, so no way to run like a Gtx 1080 video card.And mine came with a 500 FB Seagate hard drive from 2008.  Really a nine year old drive? I don't think this hp came out nine years ago.I'm making this an untangle security appliance, so I popped in a 256gb ssd drive a dual nic and installed without any trouble.If the drive had been newer and you could upgrade the power supply, I would of given it 5  stars.  But a 8 year old Seagate won't last a year...So plan on replacing the hard drive.  One very nice touch.  They included a burned copy of a Windows 10 recovery disc.  That was nice.  So reinstalling on a new drive should be easy.
