A good condition dell mini tower pc.
The Dell Dimension 4700.

It had an optical drive (IDE)
160gb HDD (SATA)
A discrete Graphics Card
A tel45 dial up modem 56k
A PCI Network Card up to 1gb
A PCIe Wireless Network Card

I picked this up for a scsi project which unfortunately this pc wont do. Not enough RAM to run the necessary software.
So the original windows install was naff, and could not be salvaged, so I installed Damn Small Linux 2025. A 700mb install.
It works surprisingly well on this system.

Would be ideal for a home nas ( with some upgrades, obviously). And comes with that monitor and 5.1 speakers. All of which are working at the time of this advert.
