Additional Components
I found two 1600 MHz SO-DIMMs inside the ASRock Beebox, used in a dual-channel configuration. That is the engineering genius I spoke of on this platform, as ASRock claims this to make the lightweight unit 30 FPS 4K playback capable. Each module is 2 GB in size and runs at 1600 MHz.
The installed 128 GB mSATA SSD certainly helps in moving your data around fast, and below it, I found the included Wi-Fi/Bluetooth combo unit.
