Description

Upd. 2026-may-03: Added new fan mounting plate (7g) with 124–126 mm bolt hole spacing and adjusted location of cable window for compatibility with various fan manufacturers.

Modifications from original:

more drives - 6 HDD / 2U to 8 HDD / 3U
proper clearance for airflow (30.5mm)
rear support
140mm fan for cooling

Rear support is 44.5mm and designed to match standard LabRax depth (~240mm). You can adjust support length to your needs by using part on 7f plate which already split onto 3 pieces and you only need to move top part to desired location and scale middle part. Or DM me.

BOM:

8x Dell PowerEdge 3.5" HDD tray
8x SATA-SATA or SATA-SAS adapters
1x 140mm computer fan
16x M3x12 screw (you should use HEX ones to avoid difficulties with mounting SATA adapters)
6x M4x25 screw (body and rear support attachment)
4~8x M4x12~20 (fan panel mount)
4x M4x30~35 screw (depending on fan thickness)
16~24x M6x12 screws (for rack mount)

STEP files are available.

Great idea. Is the rear adapter possibly also available for the 6xHDD version with 2x 80mm fans

I was thinking about using 2x 92mm fans for 6-bay version, as they should be quieter than 80mm fans, but I'll make both versions.

Replying to @IceCreamCoffeeV :

when 92mm fans are not too big, then this will be perfect. I thougt that the 92mm will be too big for the backplate. So i dont think there is need for the 80mm version

Thank you very much for this! I searched for so long, all the other hot-swap racks are either 2-bay or 6-bay, but I needed 8-bay. I was very close to designing one in CAD myself and burying countless hours into it. This is exactly what I imagined: with the support piece and the fan mount, you thought of everything! Thank you! You deserve every Boost Token I have, which is unfortunately only 1, but tomorrow, when I'll hopefully get more, you'll get another one.
