There is no way that price would be realistic… the ARK price from Intel on the board-only NUC5i5 + RAM + SSD is around $500. Then you have to add a good power supply and a fancy case for that market.
That type of price in the HiFi channel market would go for well over $1000, not including the Roon license.
Lessons here:
- Boutique hardware always costs more. No one can compete with the price of a NUC from Intel with a short life (the 5th generation above is a 3 year lifetime, not 1 year like the retail kits).
- Fancy cases and power supplies will never be offered by Intel, only boutiques.
- The HiFi channel, involving distributors and storefronts, amplify the cost of the final product.
Oh yah, and 20% off Roon is just crazy talk! Go ask Intel for that discount and see what they tell you 
… and in my opinion, Roon is worth far more than the NUC.
