PC build - Around 1k budget

[PigeonPower]

Complete PC beginner so i have no clue what i'm after but i have £1,000 give or take to spend. Possibly case and parts only if my current monitors good enough for the system.

It will be used for gaming and photoshop.

I have the below monitor.

SonicMaster MX279H 27" 1920x1080 IPS Widescreen Ultra Slim Bezel LED Monitor - Black with Bang

Prefer to have it built for me.

Windows isn't needed.

I have a 1tb hard drive already for storage so just a solid state is needed.
