Circling back to your "key factors" from your wish list. What motherboard size did you have in mind? A 24 hot-swap bay 4U chassis with 3 x 120mm swappable fans in the middle and standard ATX motherboard (downsized from SSI-EEB support from our current RM43-320-RS chassis) would still require at least around 580mm of depth. This is with just one PSU support too. That <450mm depth is physically not possible!
Sorry for the wait, I did not realise the answer until I hit this thread from a TSX31 search in case the protoype was activated
I was asking for a JBOD 4U case, ideally with 20-24 hot-swap bays and 120mm fans. A case to upgrade only the storage part (no motherboard needed), as I already have a RM51 as a server case. Most of us don't have enough space (or wife permits) to accomodate a server rack with ~600mm depth at home, while all of us have a table on/under which we could install something at the ~400mm range.
Something like the
AIC J4024 which sits at 385mm depth.
Taking your product line, it would consist of "tearing apart" the HDD cage from the RM43-320-RS, which looks great, adding a PSU to the back, a SAS controller and 2 x120mm fans, if possible, or only a grill, as the only items to cool would be the HDD with the 3x120mm fans, because the PSU would have the exhaust fan. You could make a USB JBOD or a SAS JBOD (preferred) just by changing the controller. That way the scalability would be high, as another JBOD case could be added for 20/24 HDD more, connected to the same server (your RM51, RM52... line)
Thanks for all.
Regards.
