Super Budget Gaming Server

[IDTrue]

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?

A basic quad-core with 8-12GB of RAM, and a drive large enough for an OS and the server apps/files. Ideally you'd want ethernet, but 5GHz wifi with a stable connection can work.

 

I have an i5-4670k machine with 32GB of RAM and a 1TB SSD. I use the machine to host servers sometimes, where I run the dedicated server software on Windows (Minecraft and Space Engineers, for example). Then I port forward in my router, and then it just works.

 

Edit: a 450W PSU would be plenty, a basic system like this shouldn't use over 250W at full load. GPU is not necessary as long as the CPU has an iGPU; and considering that you won't be gaming on it, iGPU power is irrelevant.

You're awesome. Thank you. I would have easy access to Ethernet. I was thinking I could just use a 240GB ssd for the whole thing. Should I use DDR3 or DDR4? For instance the used market for DDR3 ram where I live is like 25 bucks for 8gb whereas if I get ddr4 its be closer to 50 for the 8gb. is the performance worth the cost for just a server?

used 1st or 2nd gen E5 server (e5-2630), used single slot server mobo, etc.

Considering that CPUs and motherboards that utilize DDR3 are cheaper than DDR4 combos, DDR3 is probably your best option. 

A 250GB SSD should be plenty, most dedicated server apps don't need more than a few GB at the most.

You're awesome, and thank you! I don't use forums all that often.
