I'm looking to purhcase a gaming PC for my son whose 10 and myself for general family use. Budget would be approx £900 and games would be Fortnite and Gary's Mod.

The last PC I had as a 486dx and I havent a clue what to buy these days. Ideally I'd like a package to include monitor, keyboard etc and to be upgradable.

Any suggestions please. I've seen a few packages on Amazon but any help greatly appreciated thanks.
