There are a lot of ways that you can find the computer hardware you need for very low prices. Some of these are obvious choices, others are less obvious, but the result is the same: easy to find, low cost hardware. The best place to start is online. Generally, online stores will be much cheaper than physical stores due to their low operational costs. However, if you're not very keen on having computer hardware shipped to you, you could also try looking for slightly older hardware at larger stores. While software is constantly evolving, there is no reason you can't find a decent, older monitor for a decent price.
