You dont need no high end computer to host your own Minecraft Server! Something like this, precisely this, would work very well Lag Free with many mods (25-75 depending on how small and large they are) without Any issue. I highly recommend ONLY using it for that and Nothing else bc other tasks will start running in the background taking up precious CPU and RAM ypur server may need. This is 64gb of RAM and its DDR4 so you can replace the cheap ram thats inside it with better ram to squeeze out a bit more performance potentially a fair bit more if you do. You have some options with upgrading it which is nice!This could be used for home and office things, home servers, gaming servers aka Minecraft but i dont recommend gaming heavily on it lol its not meant for that but can fair pretty well with most games, i recommend upgrading the RAM if you decide to do so and remember its not a $900+ gaming pc so dont expect it do to what a mid to high end gaming pc can or should do, thats being un realistic :PI definitely dont see why you couldnt play Minecraft itself on it either, i havent done that but it should definitely be able to do so with decent frames. Ill test that and get back with the review on that.For a Minecraft Server on its own its absolute perfect! A heavily Minecraft Modded Server might wanna get something slightly more beefy (better CPU, RAM a GPU would be optional unless its RLCraft) this should be able to handle up too around 100 Minecraft Mods and potentially arpund 70-130 plugins/data packs for a Bukkit/Spigiot server.
