$1750 Gaming PC for my brother.

He plays loads of games, of all varieties.

4K or 2k gaming would be ideal.

Usually has two monitors hooked up.

Need something relatively future proof, as he wouldn't be able to change it himself.

32/64 gb ram, 1 TB nvme, etc.

I haven't built a PC in 10 years (the last one I built for him) which is why I'm coming here, and not just firing things into pc parts picker.

Please help :D
