music PC for creative work

[Endevie]

Hey! I am planning on building my first PC in a few months from now! I'll need it mostly for music production as my HP Pavilion 17 is getting less and less efficient by now, but the occasional photoshop and sony vegas will be there as well. I got a bit of an idea but no specific parts I want to save up to. That where you'd come into play.
So as I need mostly power I thought of getting a good CPU and about 32 gigs of RAM. I have an i5 at 1.7Ghz in my laptop right now and 8GBs of ram though both is not powerful enough anymore since my tracks improve and the projects get bigger. I don't really know if I will be overclocking in the future and tbh I don't really know how to and I probably won't relly need it, right?
As for GPU, I plan on gaming as well, but I honestly don't care about graphics all too much. Occasionally PayDay 2 at higher than Medium settings would be totally ok and maybe a bit of Rust and Cities: Skylines, but mostly Stardew Valley and Prison Architect and maybe all the Splinter Cell games again. I do however plan on connecting up to 3 Displays in the future as I want to have my setup in my program with two smaller displays at the bottom (about 23" probably) and a bigger TV hanging on the wall above so that I can see my Playlist inside FL properly.
I'd also need a lot of USB connections as I'm using an external Soundcard for things such as Microphone via XLR and Instruments such as Guitars via XLR, midi-keyboards, an external backup hdd (WD My Passport Ultra 1TB), my keyboard and mouse, webcam, micro USB cable of course and more in the future and I want to avoid using USB-Hubs as much as possible.
As for storage, an internal 1TB HDD should be enough, maybe an SSD for the most important programs and the OS, though I'd have to see what size I'll use.
Also a DVD writer would be extremely useful. And of course a proper Ethernet card (?), my connection is up to 100k
I really have no idea on what to use for components though.
Oh, looks is nothing important though, that thing will sit under my desk at all times anyways.
Ok, on to the Budget, that will sit at around 1000€. I live in Germany btw. I will be able to go over Budget but only for things like a bigger SSD and maybe the RAM and not too much. one to two hundred are the total maximum. Things like Windows and Displays will stay out of the budget as I will get them for free.
Oh and one last thing, please don't tell me about any offers as this is just the planning phase and I'll need up to 4 months to save up for it.
Thanks in advance for your help with this
