Description: Refurbished computers are a great choice when looking for an inexpensive machine. You know that they will work well as they have been rigorously tested before being offered for sale. On top of that, they often come with upgrades which make them as good as new devices on the market.
If you want to upgrade, see if it's a possibility while in the buying process. Sometimes, the seller upgrading the computer is cheaper than having someone else do it.
RAM, or memory, is basically how much muscle a computer has. It is also one of the cheapest and easiest upgrades you can ever hope to do. Sometimes, it's cheaper to buy a system with a little bit of RAM and then upgrade up to a higher number by adding more RAM yourself.
