Hi. I am planning on building my kid a gaming PC around my old 2070 super RTX. I've got a spare 1Tb M.2 and want to use a Lian Li Lancool II Mesh C RGB case because looks are important! 
But I am out of touch with what else to put in there. Obviously with a 2070 it isn;t going to be much more than an entry level system so how should I build it? I am thinking of a Ryzen 7 5700X CPU, maybe with a B550 Mobo? What RAM would be worthwhile? And what can people suggest for a PSU and a cooler?
Any suggestions very welcome.
