Tuvix goatsed, good ending.

I very much agree with you - I would use more fans on the outside enclosure, possibly behind more barriers so the sound is never direct (it has to bounce off walls before getting out). Eg a vent cover on the outside or simply vents mounted inside the case (not directly on the outside hole).
(Possibly also keeping the positive pressure inside the enclosure for dust control.)

However there might be an argument about HDD noise that is fairly particular to the drive models.
Maybe op just doesn’t like noisy HDDs & isn’t that bothered by fans (I centrally am more bothered by enterprise HDD noise than the noise of quality fans), so the solution is HDD-noise oriented (and I think it works in that regard).

(And yes, I do pick my HDDs by noise too.)

Depending a bit on OPs needs, this is the quickest & easiest fix I know of.

EU has a lot of fragmented (by country) road laws.

But guards/skirts are usually integrated into the design, not third-party add-ons.

Not to be confused with clopping, a pre-AI slop term mlp community uses …

Unremarkable for US. It’s specifies US breasts.

I want to know how they compare with YOUR breasts.

Exterminate on sight, even if it kills the flower.

They have shields tho, to shield their soft wares.

With even worse cable management the starship would have gotten tangled, caught in the web of Borg efficiency.

NFC where the nuts used to be.

Mmmm, queen cable manager position …

They should have assimilated PC nerds from the 2020s Earth - cable-free RGB-Borg!!

I mean, it kinda does makes sense - I always knew it was meant to portray their utilitarian nature yet thought that many loose cables & tubes was def a bit of a fashion design choice too.

Booo, I downvote this oppression!!
