Pre Built Computers?

[HarryPC4Lyfe]

Hello, I have recently wanted to buy a pre-built computer. Now before you say build one I have done so many times but I don't have the time anymore. So do you know any Pre built PC Sites with a good computer that could max out any game on High settings as well as livestream.
My Budget is £800 ($1200)

It is VERY hard to find even a decent prebuilt gaming machine, much less a good one. I would never ever buy a prebuilt gaming PC.

Is there any way you can have somebody build one for you from parts that you pick out?
