This fast, small computer comes from a pet and smoke free home. With an Intel Atom dual core processor with hyperthreading (it has 2 physical and 4 logical cores) and 3 GB of DDR2 RAM, the computer performs very well and can be demonstrated and, depending on your location, delivered and set up (at a cost based on your location). This computer is whisper-quiet, functioning properly and ready to connect and operate. It is very compact [HxWxL = 4x10.5x13.7 inches = 10x26.5x35 cm] and can be used in confined areas (such as a home theatre or student dorm) and may be placed horizontally or vertically. The hard drive contains a clean and activated installation of Windows 7 Home Premium Service Pack 1 (32 bit) and has all the latest Windows updates, Microsoft Office 2007 (Word, Excel, PowerPoint, Outlook), AVG Free antivirus software, Java, Adobe Reader and Flashplayer. Electronic copies are provided of the user's manual and other useful information. I will provide a thorough demonstration and a printed report for this computer listing all the hardware and software and benchmarking information. Here are the hardware specifications.
