Sometimes I miss the good ole dayzzz....
Chenbro RM41416 When mfg's would put everything they had about a product online.
I guess
@Defcon1 the question is how much work and adaptation hackery do you want to put into this? I think a key question is how much moolah does the seller want? IMO anything more than $200 is probably too much if you want a 16 bay LFF jbod that is semi-quiet. There's SM 836's (some adapting required), Netapp 4246's etc. etc for about that price.
About the power supply
Chenbro sold a bracket to adapt the psu frame to a mostly standard ATX (they're calling it ps2). That would probably be your most energy efficient and quietest solution if you don't want redundant power supplies... Problem is you are unlikely to find NOS or used of the
But you might be able to fab or 3d print a bracket and support collar.
Then again its possible someone on here has the right bracket sitting in a box on a shelf...
If you want hotswap psu there are more modern ATX form factor hot swaps you can get (but see above and you might even be able to adapt a SM power supply bay and pdu into the chassis if you have a donor unit.
If this was me I'd ask the seller for a nice photo of the model number on the backbplane. there's a lot of detail on chenbro's web site and you'd be able to answer th equestion SAS2 or SAS rated? That said since the backplane is passive it probably will work at least to SAS2 and with the right HBA or expander and cables you may be able to run SAS3 drives in there. SFF-8087 isn't really talked about as rated for 12Gbps per lane, but a lot of folks say it works. YMMV.
Seller including rails? you might have trouble finding them. May not be a problem if you are willing to lose a U to a shelf or L-brackets (depdning on server thickness netapp rails might not cost you a U).
Seems to me though this chassis is actually a bit of a unicorn if you were actually looking for a quiet all-in-one server (AIO). It can have a mix of LFF and SF hotswaps. You can easily get 6-10 2.5" hot swap bays utilizing the 5.25" & 3.5 optical and floppy bays. Qty of drives will depend on the thickness and type you want to support, SATA SSD, SAS SSD, U.2? All are possible. Its big enough to handle a good selection of modern GPU's. the motherboard area is large enough for dual socket and the bottom looks likely threaded for standoffs to support one. You can get an ATX psu in there and replace the fan wall so it can be made to be quiet. With the right motherboard, enough pcie lanes, bifurcation support, and some low cost multi m.2 carriers you could also have quite the nvme drive array to boot!
I think to use this a server with modern components there's some work and time involved whether as a JBOD or AIO.
If you are okay with loud and old components (you may have trouble replacing) in your JBOD and the price is right it will probably work.
