Question from a (hopefully soon) PC owner, about what to get

So I’ve been wanting to get a pre built for some time, problem being that I don’t exactly know where to start, I want something to run games really well, the reason being is that my brothers and I share an Xbox, which stays in my room, but I have been woken up too many times by them, and when they do get it, it’s for half the day, and my hope for when I get a PC the Xbox could be moved to their room, so I want something reliable, nothing flashy, just respectful here are my requirements:

1. Has to run well

2. Has to have a good amount of storage

3. I don’t really want something flashy

4. I would like for it to be a respectable build with good quality parts

5. And if you give a specific recommendation, If possible, could you send a link to where to buy it

Thanks in advance
