Regarding computer terminals (such as those that connect to Microsoft Remote Desktop Service), there is little benefit to purchasing units bran-new. Bran-new units can cost as much as a standalone PC, yet usually have no benefit over a unit procured at a fraction of the price through a site such as Ebay. The components of a terminal are not likely to suffer “wear and tear”, and performance in terminal computing is based mostly on the server and the network — not the resources of the terminal.

There is also an alternative to purchasing terminal hardware: convert your old PCs to terminals.
