The i7 iteration of the Comet Lake-based NUC (AKA Frost Canyon) is now available as a barebone for $699.95 (RAM, storage and OS sold separately). The slim version is also available as a complete Windows 10 Pro system featuring a 250GB, 500GB, or 1TB NVMe SSD.
Please note that the tall and slim versions are identical, the only difference being that the tall version supports a 2.5" drive. According to our friends over at Akasa, a compatible Turing case is coming soon.
