Satechi's Thunderbolt 5 CubeDock looks like a small companion to the Mac mini, with a silver shell and front-facing ports. The resemblance is useful rather than purely decorative. It puts the card readers and common USB connections where a Mac mini owner can reach them, while the bulk of the cables stay behind the desk.
The enclosure on the underside takes a single-sided M.2 NVMe SSD. Satechi supports 2230, 2242, 2260 and 2280 sizes, up to 8TB, and advertises transfers up to 6,000 MB/s with a suitable drive. Check that the drive has components on only one side; forcing a double-sided SSD into the bay risks damage. The SSD is sold separately.
The upstream Thunderbolt 5 connection can provide up to 140W to a laptop. Three downstream Thunderbolt 5 ports, USB ports, Ethernet, SD and microSD readers and audio connections cover a full workstation. Satechi includes the Thunderbolt cable and 180W power supply. Macworld's hands-on review highlighted the built-in storage as the unusual advantage over a conventional desktop dock.

| Power | 180W supply included |
Display support depends on the Mac's chip and available bandwidth. The dock has Thunderbolt outputs rather than a row of dedicated HDMI sockets, so some monitors will need an adapter or a USB-C input. Check the exact Mac and display combination before ordering around a triple-monitor plan.
The enclosure is the reason to make room for this cube. With a fast SSD installed, the dock can absorb a separate storage box and its cable; without one, much of its volume is harder to justify. The OntheGo hub is a smaller, portable solution when front ports are enough. I would choose the CubeDock for a workstation that stays put.
