Pentium IV 2.66GHz, 80GB hard drive, 1GB RAM, DVD/CDRW combo optical drive. This computer comes with a clean activated install of Windows XP Home SP3 plus MS Security Essentials. No time consuming software to install and update, it is ready to plug in and use. I also do PC repairs and upgrades, and I pay cash for broken screen laptops if they are recent models. My computers are priced to sell, and I spend a lot of time making sure they are in good working order, so random offers below the asking price are not welcome.
