Summary: Purchased (2) HP ENVY Phoenix 810qe Desktop computers with the same configuration for family home use. Both computers were delivered ahead of projected delivery date and functioned with absolutely no problem. Computers have been in use for 3 weeks and have taken advantage of the best features of the Windows 8.1 Start Tiles screen and Desktop. Easily customized the Windows Start Tiles and Desktop for my specific applications and eliminated unwanted Tiles and Icons.
Summary: I was looking for a sub-$1000 PC with a good base performance for gaming with potential for expansion. After some previous bad experience, I had sort of sworn off HP, but I gave them another chance with this one. End result: I am hugely impressed me with Envy's bang for buck. Pros: 600 watt power supply, really fast processor (4790!), acceptable basic graphics card (GF745), lightweight, generous HD space, not "whisper quiet" but I wouldn't call it noisy.
Summary: System works good as is but they include a water cooled I7 4770K processor which can be overclocked but there is no way to overclock with the Motherboard that comes with the Desktop. The Bios that comes with the Motherboard does not allow you to set any parameters. In order to overclock you would have to purchase a different Motherboard or somehow obtain a different Bios. I don't understand why HP would provide a processor made to overclock but you can't.
Summary: This is a very well-configured machine at a reasonable price. In fact, it is the best-equipped Windows 7 computer I could find, yet costs the same as those from other manufacturers that don't offer as many features (3TB HDD, 16+ GB RAM, BluRay, etc.) However, one of its "features" is its fatal flaw: red flashing lights. When the computer goes to sleep, the six red lines of light at the bottom of the machine flash every second or so, very brightly.
