Nica.
with a budget that nice i would contact companies that specialise in building turnkey computers for recording studios before making a final decision.. they even install the audio interface.and see what they can do for you.
(go on gearspace.com << lots of builders names)
eg....
https://www.studiocat.com/en-caor adk pro audio.
to name 2. see users recommends on gearspace.
i recommend at least 2 ssd's starting out.
i highly recommend not recording onto the drive that win resides on. use a seperate one for recording/playback//daw.
alternative i'm a big fan of cheap under 600 buk off lease pc desktops.
eg google >> "refurb ssd hp z workstation" or lenovo or dell workstation...get a 1 yr warranty.
lots of people use refurbs as recording rigs.
once again if you dont believe moi start a thread on gesarspace "recommended pc refurbs for music production'.
just some ideas.
