First off, I'm not the most tech savvy kind of guy, so I apologize if anything I'm asking for or say doesn't make sense.
I was looking to build a cheap gaming server that I could leave on pretty much 24/7, to host games such as Minecraft or GMod. I have hosted games before using my own rig(7700k, 1070, 16GB Ram, Internet: 1000 mb/s down and 40mb/s up ) using Hamachi. But I hated leaving my pc on all day all and all night for my friends, and there was always the sketchy vibe when giving my friends my IP address and some friend of a friend wanted to play too and I was weirded out giving it to them. Anyways, I always see these super budget Pc builds on reddit and YouTube, and I've wondered if there is a budget server I could build/ buy. There are some things I don't know like: Do servers need a gpu? How much electricity will it use if I were to build one? Is it better to just pay the 7 dollars/month on one of those Minecraft server renting sites? I'm just not sure what my options are and I'm hoping all you tech savvy people could help me out?
