First, don't buy this if the peripherals such as the mouse and the keyboard are important to you.  The computer itself didn't have a scratch on it and worked (with tweaking since it came with Win 10 but was built for Win 7), but the mouse looked like someone had ground the top of it in gravel-totally chewed up, and the keyboard was taped together with brown packing tape, so just toss those!  Realize that if you need a simple email and web surfing machine, this is fine.  These are old machines and are way beyond any support from H-P.  Plus the only drivers that H-P offers are for Win 7, so you'll need to know how to surf the web and update as needed on your own-there are programs for that.  For gaming, you'd need to add a good graphics card (low profile only), and an SSD to replace the slow 5300 RPM Western Digital HDD, but in the long run, that expenditure isn't worth it on a machine this old.  Also, you'll only be able to add an SDD IF you're familiar with bios settings.  Crucial says it can't be done-it can- but will take some time and effort.  If I had it to do over again (and I might), I'd spend another $75-100 and get a newer and nicer machine.  This one worked in a pinch on a tight budget as a hurricane wiped out my last one.UPDATE AFTER 5 WEEKS:  I'm returning this to Amazon.  The power supply fan is squealing and the hard drive clunks like and old farm truck.  I was willing to overlook the damaged junk peripherals, but not the computer itself.  It's just too old to expect any longevity.  I'm not soured on the refurbish program, but it's probably best to spend a bit more money for a newer model with "less miles" on it.
