We replaced an 8 year old household computer with this Optiplex.  I really like that it's super small, it's quiet, and it just works.  We use it for general household use, 98% in Chrome (banking, email, calendar, homework, maps, surfing, light photo editing, scanning/printing, etc.).We already had a good quality Dell 27" display with built-in speakers, microphone, and webcam, so I connect to that with an HDMI cable (which brings video and sound) and a USB cable (the USB provides connectivity for the camera, mic, and the display also has a usb hub built-in which is useful for the keyboard and mouse).This Optiplex came with a Dell wired keyboard and a wired mouse, which I actually prefer (wired = no batteries, no charging), and they work really well.I did add a 8GB ram stick to bring the total RAM up to 16GB, but I don't think it was really necessary, as the computer was working great without it.  I do think having 16GB might prove useful if we keep this machine for 8+ years like we did our last, and it was pretty cheap to do.
