This a replacement for my 9 1/2 year old Dell Inspiron PC. As with most PCs, 70% of the cabinet is unused and the unit takes up so much space unnecessarily. The unit operated fine, but there were MANY Windows updates that needed to be applied, including a very large one that took several hours through 3 unsuccessful installation attempts. This is no reflection on the seller, or Acer, but what a big bother to need to deal with this on a brand new product. Windows 11 is due out soon, so maybe this troublesome Windows 10 update will soon be unneeded anyway.
