In 10 years of streaming I’ve never put a computer in my audio system. I’ve always found digital benefits from low noise and low power, which is the opposite of how consumer computers like the Mac mini are designed, and you can strip bits out but you are stuck with the operating system.
My set-up is as simple as it can be and mostly fibre-optic, with no switches, routers or wifi, and ultra-low and clean power, with the power distributor and server on vibration isolators.
