Hello, I have a Dell SX270 desktop computer for sell. It is a small form factor, actually a very small computer so if space is a priority then this is for you. I recently formatted the computer and installed Windows 7 Ultimate and also includes Microsoft security anti virus protection which is free for life of the computer. It has a Pentium 4 2.70 GHZ Processor, 30 GB Hard drive, 1 GB memory and a cd rom drive. This is not a pirated version of Windows as you can see it is activated in the photos. For an additional 10 dollars, I will include a wireless USB stick so you can wirelessly surf the web. A great computer for surfing the web, Facebook, or Skype. This is for the computer only, no mouse, keyboard or monitor. Computer is fully updated. All you need is to plug in to your existing monitor and go. I will take lower offers but I will format the computer and no operating system will be included.
