Only downside: the supplied VGA screen with a VGA cable but the VGA connector on the PC is not functional (the HDMI connection with my TV allowed me to realize it). We must therefore buy a VGA to HDMI converter is not provided.
Silent and fast machine: large disk, large RAM, quad-core to 4Ghz - the setting is comfortable. The screen is of good quality. The transparent tower with blue neon "throws" in the dark.
A purchase I not regret.
