Refurbished technology such as refurbished servers from PerfData.com can save a small budget. Refurbished equipment works just as well as used equipment. Most of the servers will come with a short warranty in case something happens.
Servers cost a lot of money. They are not single computers that are used in a family home. They are used to store millions of files and information. Many companies have dozens of servers running at the same time. They stack on top of each other inside of a glass case most of the time. There are wires running everywhere. Most of them are filled with lots of memory to keep up with the demands they need to meet.
