Very Fast and Responsive Computer! We've Been Using These at Work for A While Now, Had to Get One For Home Now. The Only Problem I Had was That the Mouse Supplied Would Not Work... I Tried it On a Different Computer and Nothing Either... Bought a Logitech Mouse and All is Well. Operating System is Installed on SSD, Boot Up is Fast!!! CPU is Exactly as Described Otherwise. Obviously Case is Used, But Who Cares eh? Good CPU for the Money!
