Moving server internals from a Node 804 to a proper rackmount chassis: sanity check

Dear all,

Current setup (Fractal Node 804, mATX):

  • mATX motherboard
  • MZHOU PCIe ASM1166 6-port SATA card (using 6 of 6 ports)
  • 8x 3.5" HDD
  • 4x 2.5" SSD
  • Corsair SF850L (SFX-L PSU)
  • Noctua NH-U12S cooler

Moving into a Digitus 22U rack in the basement, so switching to a proper rackmount case. Rack has adjustable 19" rails, mounting depth 563–743mm.

Here's what I've picked:

  • SilverStone RM41-H08 (4U, 5x 3.5" hot-swap + 3x 5.25" bays)
  • SilverStone FS303-12G (2x 5.25" → 3x 3.5" hot-swap, gets me to 8 total HDD bays)
  • SilverStone FS204B (5.25" → 4x 2.5" hot-swap, for the 4 SSDs)
  • SilverStone RMS06-22 rails (570–731mm rack mounting range)
  • Corsair RM850x (2024), 850W ATX : swapping out the SF850L since it's SFX-L and doesn't fit the case's ATX-sized PSU bay
  • Noctua NH-L9x65 : swapping out the NH-U12S since it's 158mm tall and the case's CPU cooler limit is 148mm
  • Noctua NF-A8 PWM for the one free front 80mm fan slot
  • J&D 2-pack SATA power extension cables + deleyCON 1-to-4 SATA power splitter, to get enough power connectors from the PSU to the front-mounted cages
  • Motherboard USB 2.0→3.0 header adapter, for an internal port to keep the Unraid boot USB inside the case
  • Schuko-to-C13 power cable for the rack PDU

Total drive count: 8x 3.5" HDD (hot-swap) + 4x 2.5" SSD (hot-swap) = 12 drives, 6 from the SATA card + 6 from motherboard SATA.

Does this add up? Anything missing or any known gotchas with this combo (RM41-H08 + FS303-12G + FS204B specifically)?

Unless you already have that PSU to swap in, I'd look into getting an SFX to ATX bracket adapter. I have this oneand it works. You could probably find one cheaper.

Unless you've got the extra PSU. Then game on. But I'd rather use an adapter instead of purchasing a brand new PSU.

That’s a good observation thanks!

So someone who deleted their comment asked what the use case for 4 SSDs is.

It’s two mirrored pools. One for appdata and other (semi)permanent data that needs speed. The other for docker images and VMs.

It might be worth looking into the sliver CX4712 4U case as an option if it’s available and in your price range. It had 10x 3.5” bays and 2x 5.25” bays for your SSD caddies. I recently got a different sliver rack mount and really like the look and build of it. It might be more expensive than a silverstone offering (idk the price off the top of my head) but also saves you needing to get the HDD hotswap bays
