spinaltap,

The implications are that Roon is far too expensive however, after a quick search on Amazon UK I came up with the following which assumes you have no hardware you can utilise for Roon and need/want to buy all new, secondhand equipment is also available on Amazon.

You could of course spec a higher performance NUC at more cost if required but the i3 is closest to the Innuos Zen mini albeit still much faster performance as per the following performance results.

Latest 8th gen i3 NUC £264.14

Crucial 8GB DIM for NUC £34.97

240GB M.2 SSD for NUC £30.99

USB CD-ROM drive £20.99 (ROCK supports automatic CD ripping via a USB CD-ROM, if you use dBpoweramp or similar for ripping you could save the cost of this.)

External 2TB USB drive for music library storage £54.93

ROCK operating system £0.00

Subtotal £406.02

Roon lifetime licence £402.53 (at today's rate of $1.21 to £1)

Total £808.55
