If you have a budget that high, I'll be happy to help you plan out the entire setup and not just give a parts list. Feel free to message me directly or through my modding page, NGEN-PCs. Everything from parts choices, to the peripherals, to even loop layout.
If u truly got that cash then invest it into something worth while, all electroics do is depreciate. i wouldnt spend over 3k on a pc ever.. Full water cooling the works. Can be even done for half that price .
