I've been hosting a desktop server on weekends for minecraft with friends (<10), and I am wondering how much it would cost to get a home server to host it 24/7. I know computers fairly well, but do not know much about servers. I run some bukkit plugins, and have recently heard of Spigot, which is supposedly very optimized. Could I get an estimate of how much this would cost, and maybe even some recommendations? Thank you very much.
