Is it worth it to build a home server for Minecraft?

Since I like building PCs I thought of an interesting project which is building a cheap server for the 2 week Minecraft phases of me and my friends. Because all of the free server hosting websites are shitty and allow rendering only like 4 chunks I wanna have something that allows me and up to like 4 other people to have a not laggy experience while having a decent viewing distance and so on. I (most likely) won't be using any mods tho. How much money would I have to spend for this (I'm cool with buying used as I really want to keep the price as low as possible) and what are other problems I could run into? Is this a stupid idea?
