I was quite happy with the previous Inter-Tech case I got, so I decided to get another. This time I got a rack mountable storage case, with 16 hot swap bays, for my file server Zeta. More thoughts and photos!

YouTube review of a similar case: https://youtu.be/swWgav-p2Nw


4U, 688mm deep
Form factor
Drive bays (mounting options)
2 × 5.25" external
16 × 2.5" or 3.5" external (hot swap)
2 × 3.5" internal
8 × 2.5" internal
Fan mounting options
3 × 120 mm, internal
2 × 80 mm, back


What I like

  • Lots of space
  • 3×120 mm and 2×80 mm fans included
  • Internal fans are hot swappable and can be PWM controlled
  • Two 4×2.5" disk trays
  • Was able to replace the stock fans with Noctua

What I don’t like

  • Stock fans are loud (but move a lot of air)
  • The 5.25 rail mechanism feels a bit cheap and flimsy
  • Had a hard time attaching 2×80 mm Noctua fans. Had to grind off a screw thread on the case and modify one of the Noctua fans
  • Break-away expansion slot cover plates
  • The backplane felt slightly misaligned on the right side, disk did not go in as smooth as I would have liked
    • I was able to fix this by loosening the backplane screws, and re-tightening them while the drives were installed
  • Screws for mounting drives in the trays are really short
  • Found a loose part in one of the drive trays?!


I replaced all stock fans with Noctua.

Internal fans

120 mm Noctua fans fit perfectly in the hot swap brackets. But they will need a 4-pin header to be able to fasten it.

I’ve written a dedicated post about the mysterious 6-pin fan header.

Back fans

The two 80 mm Noctua fans in the back was a tight fit, I had to grind off a screw thread and make a groove in the right Noctua fan.
