£5k Budget, help please.

^ this.
A 2.5-3k machine should be more than enough to keep you playing games at the highest spec for the next 3-4 years. If you feel you need more power later down the line you can always upgrade. Spend the rest on a chair/desk and treat yourself to a nice holiday

@UP Please skip the NZXT case, it's pure plastic...

The Switch 810 is still a quality case even if you can get better ones.

I just picked it because it supported 360 + 240 rads.
Better suggestions are always welcome, especially ones which support thicker rads

On another note, while I generally agree with most of the guys above, I will say that you're picking what you would buy and not what the OP is asking for

Agree, not seen anything to suggest the Switch 810 isn't a good case.
