Well thought out and qualitative accessory
This storage bay allows to embed 4 HDD/SDD in a 5 1/4 slot ... perfect to transform an old box into a personal server taking no space (personal openstack server from an intel core i5 10400T / 24 GB of ram).
Practical: the bays occupied by a disk are indicated by a blue LED.
The only 2 small drawbacks that I find for the moment:
- The disks do not have an activity LED
- although they seem solid, the bays are made of plastic; but they are not supposed to be dismantled several times a day so I won't hold it against them
In view of the above comments I have decided to get an extra 40mm Noctua fan. I'll see how the original one performs over time and if it needs to be replaced before its end of life.
