Overall, this desktop is great for the price. It has 8 USB connections and 4 expansion slots. Haven't tried the expansion slots but one of the USB connectors didn't work.  It has a DVD disk player which works.  So far, I can't get my Canon MG2522 to work with this desktop but I'll keep trying.  The Intel i7 is very fast.  It came with Windows 10 which I wanted.  My software won't work with Windows 10S or Windows 11.  However, it has cosmetic damage.  Not a deal-breaker but it shouldn't have been listed as "excellent" condition.  It's really huge and takes up most of my desk.  Very heavy.  It's a really old model HP with new innards.  It came with a 2.4 wifi adapter which works but is slow.  I purchased a wifi adapter that's much faster and works well with the desktop. It didn't have a memory card reader so I purchased one of those.  I use trail cameras that require memory card readers. I also purchased a hard drive adapter so I could transfer/use files from my dead laptop.  Don't know how long it will last but, for the price, it's been a great purchase so far.
