Very nice computer for the price. No problem setting up and registering the windows 10 pro. There was a keyboard but no mouse included which wasn't a problem for me as didn't intend to use either a generic keyboard or mouse. Should be aware that this was a business computer used in a commercial environment. I ran tests on the memory and 2 TB disk drive, both where good but the disk drive had 5+ years of almost 24 hrs a day run time with power cycles only every few weeks. Looking at failure rates for similar drives on line suggest that this should still be reliable for several more years. However I made a system image and backup just in case immediately after setting up the new windows 10 software.This has a Q87 intel business chipset not the Z87 series most gamers are familiar with doesn't support over clocking but what the heck this is a fast enough machine as it is. Compare this to a new HP i7-7700 2.9 GB/s desktop with 8GB memory at BB for $800 and you get a slower 9266 vs 9780 CPU Mark computer, half the memory, without the pro version of windows 10 and the BB one has only a 180W power supply compared to this one's 320 W active PFC . A small negative the optical CD is a slim read only mounted vertically, you read your old CD's but not burn any new ones.Should mention that HP website supports this with excellent manuals, bios updates and community support for questions.For the price a 5 Star!
