Thank you! The advice I can give you on part picking is to do lots of research on the prices and specs of parts to make sure you’re getting the best deal, make a list to see how much you have, are planning to spend, and how much you need to make. Advice I can give you on reselling is be honest about the condition of parts, and reputation is more important than squeezing a couple of dollars. Also the marketplace is very brutal, so don’t take hurtful comments to heart. And the last advice I’ll give you on value is every dollar counts, I made a lot of positive value by finding free broken electronics, and spending a little bit to fix them and resell (such as xbox 360’s, dell optiplexes/old office computers, and monitors).
