Cheap JBOD enclosure?

Hi all,

Long time lurker here. I've recently had some hardware failures I my home lab (yay 😥) so am looking at improving my setup from janky to more acceptable...

I currently have 8x 3.5in HDDs as part of my unraid NAS. I am looking at a new enclosure for these. I don't need speed, but am sensitive to power consumption.

Has anybody used anything like these? https://a.aliexpress.com/_mr3YgR9

They are in the right sort of price range for me. I understand airflow will need to be addressed, but have a plan to have fans setup at the rear with a shroud to suck air through the enclosure. I also have an efficient power source for 5v and 12v to run them off.

Any thoughts?
