Very fast and quiet computer and stays cool even though it sits in a computer cabinet of my desk.  My old HP tower would heat up like a heater was in the cabinet, but not so with this Acer Aspire.I have an old HP monitor from 2010 without an HDMI port so in order to plug it into the Acer was buy a $6 "VGA TO HDMI ADAPTER" (I got at Walmart for $6).  Just keep the old clunky VGA cable plugged into your old monitor like before then attach the "VGA portion of the adapter to your VGA and then plug the HDMI end into the Acer.  This computer is just as fast as my HP and for 1/3 the cost!CONS:  keyboard and mouse that comes with this are good to set up the computer then afterward set up your wireless keyboard and mouse you must buy separately.  I went and bought a lighted up keyboard and wireless mouse but didn't connect them by BLUETOOTH until AFTER I did the initial setup with the wired keyboard and mouse that was included.  They seem to be just disposable ones for setup only since they operate at a very minimal rate but do get the setup job done.
