I purchased it last year and it's still in excellent condition, minus some wear on the keyboard / mouse.
Box and manuals are included.
Due to a recovery partition, the hard drive can be formatted; and windows 7, along with all factory installed software, may also be reinstalled with ease to make it your own.
To save space all information regarding this PC can be found on its product support page located here:

The included video card is an ATI Radeon HD , which I've found to be perfectly fine for most games using default/medium settings.
