I've been purchasing HP refurbished PCs from Amazon for about 10 years staring from PC with Intel Dual Core CPU, and have been very happy with all the PCs I purchased. I especially likes this one with Intel's I7 sixth gen CPU and 32 gb of ram. Some reviewers mentioned difficulties upgrading with video card and other peripherals, but I am not a gamer so I don't need to upgrade the video card. I do have a 11th gen Inter i7 laptop, and I don't feel any difference between the laptop and this PC in what I'm doing. I do have one complaint about one Display Port not working properly, but otherwise I highly recommend this PC. I don't see any reason to pay over $500, even over $1000 for brand new computer if you just use your pc for browsing or works with words or excel. I do use this PC for web programming, and I don't experience any lag or any other problems so far.
