when my son built mine, end of last year, Frst of all is setting a budget to work to. It is all too easy to get carried away building with expensive parts and run out of money to complete.
One important thing is the case and consider airflow . the cooler a computer runs the better. So I would suggest getting one with fans at the front and back. Some cases have side vents and this slows down air flow considerably. there are so many parts and if you mess up with the processor with wrong amount of paste for example, when putting it on the motherboard !!! also the PU (power unit) needs to be big enough handle the load and a graphics card up to the job
A for componants my advise would be to ring contact the suppliers we use “Scan computers” who are verfy helpful. tele no [ 01204-474747 ] https://www.scan.co.uk
You can give them the budget to select the components for a gaming computer.
However if you go on their site you may well find what your already built which is what I would recommend.
Price wise to get anything half decent with a windows based computer as self built your starting budget I would have thought anywhere between £1000 to £1500 upwards
the build on mine
Apart from canniblising the 750w PU and graphics card plus a few other bits and pieces
This is first look at components for a self build.
1= [be quiet! Pure Base 600, Black, Mid Tower Computer Chassis, 140/120mm Fans, USB 3.0, ATX/Micro-ATX/Mini-ITX]
2_Noctua NH-U12S SE-AM4 Ultra-Quiet Slim CPU Cooler, 1x 120mm NF-F12 PWM Fan, Copper Base/Heatsink, Aluminium Fins, AM4
3= 32GB (2x16GB) Corsair DDR4 Vengeance LPX Black, PC4-28800 (3600), Non-ECC Unbuffered, CAS 18-22-22-42, 1.35V
4=[Windows 11 Home Edition, 64-bit, English International, USB

hitting just over the £1000 target, if that is any help, remember the PU and graphics card I already had.
Then there is the question of a monitor to produce the best and can handle 4K or higher
