Had a recent conversion with Norco and got the following. They plan a preassembled chassis for just adding drives. Something like the 16 or 24 bay case with PSU and Norco branded SAS expander. The SAS expander would be a PCI slot expansion card with a Molex power input and being able to turn on local PSU depending on incomming signal, very similar to the Chenbro unit sold out everywhere. And they confirmed that they are moving to 120m fans, lets see when we are going to see all this.

 

So, clearly, we need support for more Volumes and SAS in unRAID.

If you happen to speak with them again, could you see if the 120mm plates would be backwards compatible with the 4220 or 4020?  I've been lazy and haven't felt like creating a new custom 120mm plate for my 4220.

I talk about that one as I already have a 4220, they were evaluating and not clear on this one.

the 4220 is going to be updated to 120mm fans in q2 i believe, maybe jsut sell your current one and get a newone

It is not clear but most likely Norco will sell the 120mm fanboard as an upgrade to existing 4220 cases. I would much more prefer this route instead of pulling everythig out the case and migrating into new one, just to get 120mm fans.

Well I guess I can always use a 4220 for my WHS that I'm going to use for OS images and general document storage... but 20 bays is a bit steep for my intended use.  On the flip side, if Norco doesn't want to sell the plate alone and there is enough demand from the community, I'd be willing to have a machine shop make a run of custom 120mm plates. 

 

(My fiberglass 140mm plate is nice and all but fiberglass is very fragile at the thickness required for the top screw mounts. The 4020 was at good in the fact that the plate was attached by screws in the side of the case.)
