this product is a Lenovo 3000 tower with the CPU being an Athlon 64 x2 3800+ whitch means it is 2GH'z x2 = 4 Gh'z.
the motherboard this is in and the CPU spourts 64 bit operationg systems whitch means more stabilty and less crashes.
the 1GB of ram lets this system down but this syatem can easliy be upgraded depending on how many DIMM slots is in the motherboad if you chose over 2GB you would need Windows XP pro x64 edition or vista (any vertion 64 bit ).
the hard drive is the normal 3.5" runing at the normal 7,500 RPM this hard driver is 250 GB
has a standard DVD-writer that would burn CD and DVDs
has the stardard vertion of XP
has no monitor but there will be some packages out there that will include one i would recomend and LCD 19" widescreen
this pc would be an ideal ofice or work pc this is not a gaming pc becuase it does not have a grafic card (built in grapfic on the mother board)
