Are you aware this is just the PC tower, no monitor, keyboard, speakers etc?
I also notice it has the 64 bit version of Windows installed.
Unless you are in to computers I would steer clear of 64 bit Windows for now.
Most people in the world run 32 bit Windows and all the software, drivers etc are tested under 32 bit Windows but sometimes 64 bit Windows can cause problems.
There is no doubt we will all be running 64 bit Windows in a few years, but at the moment it is still a bit leading edge.
