Reviews
I love how fast this mini PC runs my editing software. The graphics handle 4K video without any lag and the extra storage slots give me room for all my projects. It stays quiet even when I push it hard during long sessions.
Setting up multiple screens was super easy with this little machine. WiFi stays strong and the processor manages my daily office work plus some light games really well. I just wish the fans were a tiny bit quieter at full speed.
The compact size fits perfectly on my desk but still delivers desktop power. Connecting an external graphics card through the special port boosted my gaming experience a lot. Everything feels smooth and responsive for work and play.
