+This HAT includes four SATA drive connectors, plus one edge connector for a 5th drive, 12V power inputs (molex or barrel jack) to power both the drives and the Pi 5 via GPIO, a cable for the 5th drive, an FFC cable to connect the HAT to the Pi 5, and screws for the mounting.
+
+There's also an 'Expansion interface' with connections for OLED and Fan control, but there is no included adapter for such purposes. So you'd probably want to connect a little fan to the Pi's fan header for the Pi itself, or a USB fan for the drives, if needed.
+
+It looks like the SATA controller is a JMB585 PCIe Gen 3x2 SATA controller, so it could benefit from running the Pi 5's PCIe lane at Gen 3.0 speeds (setting dtparam=pciex1_gen=3 in /boot/firmware/config.txt).
