Fanless Enclosure / FS-1021
3U Fanless Enclosure for Mini-ITX
The 3U fanless Mini-ITX that adds slim ODD and two 3.5" hot-swap trays on the same 16.90 × 5.10 × 10.40 inch body as FS-1020.
Product Overview
What the FS-1021 is built for.
FS-1021 shares FS-1020’s 3U Mini-ITX envelope, three PCI/PCI-E slots, and 120W/19V + C4 150W power, then puts a slim ODD and two 3.5" hot-swap trays on the front. Choose it when the 3U fanless node has to carry spinning storage, not just cards.
