The desktop runs perfectly; great purchase, especially for the price.  If you are an amateur computer guy like me, you'll find the Acer design very easy to work with in upgrading the PC.  I have already upgraded the RAM from 12GB to 16GB and added a 6TB internal HDD.  Each was performed easily and quickly (check out youtube videos for assistance).  Acer design made the job much easier.  Plenty of space inside PC and you can easily get to everything you need to replace or upgrade.Would definitely recommend this PC to anyone.
