PC Recs? (pics are inspo - not mine)

I’m looking to buy a PC and i have no idea where to start so i was hoping to get sm recommendations and advice etc (apologies for any poor terminology)

I’m also open to building one if that makes anything easier - I’ve never done it before so i’d be looking for tips/ youtube videos to help

Im looking for:

\-Under £2500 (preferably)

\-White / Matcha Green colour (more so green than white)

\-Those like coloured fans? (are they fans idk)

\-Cute but high quality

\-High speed (like no lag)

\-Lots of storage (and i mean LOTS)

\-Good for photo editing, music (like using logic etc), and games

\-The pics at the top are some inspiration, not so much the colour just the general vibe - ik they’re all built rather than bought so i’m not really expecting to find anything like that ready built but as close as i can get would be great - or links to parts to build my own, i’m not really sure what i’d need to build my own but i’m open to it! (it won’t let me add pics but this has also been posted other places with the pics attached)

If possible please include links!!

Thank you so much for all your help :)))
