If you have been thinking about buying a new desktop, you might be interested in an all-in-one system. They are easy to deal with and don’t take up much room at all. The Dell Inspiron One 20 in particular is a good choice due to its sleek profile. It’s incredibly thin with a system depth of 2.49-inches. The edge is only 1.36-inches. Since it’s compatible with a wireless mouse and keyboard, you won’t have to worry about wires hanging all over the place.
