I'm actually very interested in these - could you point me at some? I've been interested in getting a NUC8 machine, but the cheapest I can find one for (granted, in the UK) is £750 before RAM & SSD... and I have been seriously considering the new Mac Mini as a result because the final price doesn't seem like it'll be much different.
edit: found some on SimplyNUC.co.uk starting at £650 (inc VAT), 8GB of RAM and 128GB SSD, awesome! https://simplynuc.co.uk/8i7beh-full/
