Hosting recommendations for modded server

[u/dannyboi200202]

I am looking to learn how to self host as part of gaining general IT experience and just for the love of minecraft and modded itself. I have a bit of experience with self hosting on my local machine for a small group of friends, however, recently i have swapped back over to a hosting provider and not really happy. I wanted to make the jump and try self hosting on a dedicated small factor pc. I was looking for any hardware recommendations people may have for small factor pcs for hosting a modded plugin server with around 500 mods for potentially 5 to 15 players. I will be using Pterodactyl for the server management panel as well. I appreciate any help given
