NUC is a single board computer :) If you think the price is high, I would point out that the SSD I used cost €200 new when I purchased it back in mid 2022. A used 120 GB SSD by contrast can be had for maybe €10 which alone would explain the difference in cost. Now if 120 GB is enough for your application, that's a good value so more power to you.
