Questions about this item

What clearance does the 10.6 x 3.7 x 12.1 in SFF chassis need on a desk or shelf?

Allow at least 10.6 in depth, 3.7 in width and 12.1 in height plus extra space around the air-cooling vents for proper airflow.

Which cable do I plug into the rear DisplayPort and which into the HDMI 1.4 port for dual 4K monitors?

Connect one monitor to the DisplayPort and the second to the HDMI 1.4 port; both support 4K output from the Intel UHD Graphics 770.

How do I add more storage later if the 512 GB SSD fills up?

Install an additional M.2 NVMe drive up to 2 TB in the internal slot; the board supports PCIe NVMe SSDs for expansion.
