Lenovo IdeaCentre Q190 57326004 Desktop Computer
This nettop has an Intel Celeron dual-core CPU which is pretty good in a small system like this. It has 4GB of DDR3 RAM, though you can't upgrade it to more which is one of the few negative aspects of this system. The 500GB hard drive in this one is decent, though not stunning, so keep that in mind if you think you might need more space. This nettop has Wireless-N connectivity and an Ethernet port, but not Bluetooth.
Although it has an integrated Intel graphics chip, this nettop lacks any dedicated video memory. This pick does include a USB keyboard and a USB optical mouse which is great for easy input but the internal power is just a bit weak for serious PC gaming. Rounding things out are four USB 2.0 ports, two USB 3.0 ports, and an HDMI connection.
