The integrated Intel HD Graphics 2000 and included WiFi USB adapter support general productivity and web browsing. Gigabit Ethernet provides wired network connectivity. Buyers who require a dedicated graphics card for modern gaming or intensive 3D work should consider a different system because the SFF case and integrated graphics limit expansion options.

Questions about this item

How much heat and power does the i7-2600 draw inside the SFF case during long sessions?

The Intel i7-2600 is a 3.40 GHz quad-core processor with 3.80 GHz Turbo Boost; the compact SFF chassis relies on its integrated Intel HD Graphics 2000 and a 256 GB SSD that generates less heat than a mechanical drive.

What must I already own to use the included USB keyboard, mouse and WiFi USB adapter?

You need a free USB port for the keyboard, another for the mouse, and a third for the WiFi USB adapter, plus a monitor with a compatible video input for the Intel HD Graphics 2000 output.

Can I keep my older DDR3 memory modules and add them to the 8 GB already installed?

The system uses 240-pin DDR3 DIMM slots; you can expand up to 16 GB total, so existing DDR3 modules that match the speed and voltage will work alongside the installed 8 GB.
