Found this prebuilt on BPC seems decent for those in the market for a 12th Gen + RTX 3080 system
total for individual parts on AU PCPartpicker $3558 even factoring in recent price drop in GPU and Ventus going for $1899
Update 20/2/21- V1 version no longer listed/available - they've replaced it with a V2
AIO model replaced to slightly cheaper - EVGA CLC 280 RGB LED 280mm Liquid CPU Cooler with NZXT Kraken X53 73.11 CFM Liquid CPU Cooler
also seems to be option to choose PC Case Colour between black or white
