I assumed when I ordered this that this was one of those refurbished items that was purchased and returned by someone else for a minor defect.  This computer is fairly old (the case and the motherboard, anyway).  The HP website says this model won't run Windows 10...they are wrong, as it runs very well.  The case has a small chip on the front.  The only real issue would be the Intel drivers...as they have not been updated since 2015.  This probably won't be a problem, but it is something I wish I had thought about before buying it.Setting that aside - the performance is excellent.  The hard disk is an SSD, and very fast.  I ran stress tests on the disk, CPU and the memory, and had no issues.The included wifi dongle is junk, though.  There are a number of better ones on Amazon for under $20.
