Is it easy to set up a home server?

[Jake Horsfield]

It depends, if you are wanting to set up a web server for personal use e.g. testing, then it should be okay, but if you're wanting to set up a web server to run a website with regular traffic, then you'll run into problems as your hardware won't be good enough.

Another thing to think about is your ISP. I doubt that you'll be allowed to run a web server from your current plan with your ISP, you'll have to upgrade which will cost A LOT of money.

If you're planning on running a website which you want people to visit on a regular basis, I'd recommend that you just buy hosting. This way, it would be much cheaper, you wouldn't need a PC running 24/7 and you'll be more relaxed as there won't be a ton of problems you need to fix.
