May I suggest adding this unit to the list of Roon Core Kit compatible servers?
It’s barely bigger than the NUC’s, fit’s a full desktop Skylake I7 6700 processor, has both an M.2 PCIe SSD slot and 2 SATA ports for dual 2.5" drives for storage. The new inexpensive and blazing fast Intel 600P M.2 PCIe SSD’s can be used for the OS:
And dual spinning hard drives or SSD’s for file storage up to 8tb. It’s readily available world wide, and costs even less than the Skull Canyon NUC when equipped with the I7 6700. Even less with the I5 processor.
I compared it head to head with Skull canyon NUC as a Roon/HQplayer server, and running the most demanding HQP algo’s up-sampling to DSD 256, both average 30% CPU load.
Noise wise running Hqplayer at 30% CPU is less than the Skull Canyon NUC. The cooler has much more surface area and it’s very well ventilated.
