The best thing you can do for yourself when you are shopping for any computer hardware is to determine what your own specific needs are.
When you are deciding on what to purchase for a display appliance start by asking yourself a few questions.
1. What is my budget?
This is an investment and, as is the case with most things, you get what you pay for. If you pay for higher quality, commercial grade hardware it will most likely continue to suit your needs for years. If you choose to spend less, or opt for lower quality machines you may need to replace or upgrade the equipment in a shorter period of time. Either option will work, this is a personal choice and is completely up to you.
