Help me build a linux audio workstation and home network storage server

I want to build a linux PC for digial audio and home network storage.

I plan to use a microphone to record acoustic instruments, so being quiet is a priority. Also, my usb audio interface and usb MIDI devices should be plugged in directly, no using a hub, so a lot of usb ports is another requirement. I'm not clear on whether my devices take advantage of usb3 speeds, but I think I'd better make sure I have more usb3 ports to use that speed if it's available.

Besides that I'd like to run a storage server for my home network. I'm not sure if this is a good idea on the same box I want to record on, but usage should be pretty light and I don't want to build a whole other device for this.

I have an older graphics card already, so I don't need that. I'd like to have a slot available in case I decide to get into experimenting with AI, but that's not in my budget for now.

I'd like to keep this under $1K. What parts should I get? It'd be extra helpful to put together a list in Micro Center's PC builder, since that's where I'm tentatively planning to pick up all my parts.
