The Crimson Canyon NUCs are meant for users who do not really intend to upgrade their systems, as the RAM is soldered and there is already an HDD included. Users may still choose among 4 or 8 GB of LPDDR4-2666, however, there is only one CPU option - the 10 nm Core i3-8121U. Also included is the Radeon 540 GPU and users can add more NVMe storage.

Definitely a good tiny HTPC and office PC with some capabilities for basic light gaming. Would be better with an RX550 instead of a RX540, but I'm getting greedy heheh ;D ;D
