I purchased the HP EliteDesk 800 for general home use.  The Intel Core i5 4570 is a workhorse and a great improvement over the old computer it replaces.  I find the 8 GB RAM sufficient and the 500 GB hard drive is quick enough for now.  There is room to add another drive if I need more storage.  For now I'm using Microsoft OneDrive cloud storage.  The computer arrived with an intermittently inoperative CD/DVD drive.  I emailed the supplier, MyTechnologyGeeks and they sent me a replacement overnight.  It took only a few minutes to replace.  That's one of the nice things about these HP SFF computers, no tools necessary for most service.
