I would definitely second (third, fourth) the recommendation for a Supermicro 826 12-bay chassis, they are great, and easy to quiet down.
However, AFAIK, the AOC-SASLP-MV8 you are planning to use is not only a Marvell based controller (although one of the few good ones which is not highly problematic), I have heard multiple people say it does NOT support SAS expanders, so an 826 chassis will need a direct -A or -TQ backplane to work with that controller.
That said, is there any reason you don't want to use an LSI SAS2 HBA?
I'm not sure, but the linked auction is just over $400 shipped to the SF Bay area, made worth it as others have mentioned because the PSUs are the excellent quiet SQ model, which bottom out at ~$100 shipped each! Things get even quieter and more efficient if you only run with one PSU BTW...
I haven't had time to overhaul my FS/FT posting in a while, but I have a few of the 826 chassis I don't need anymore and all of the relevant backplane options and SQ PSUs too, as well as some quiet replacement fans which work well in these chassis' - PM me if you want to work something out for cheaper than that listing including either the TQ or A backplane for your AOC-SASLP-MV8 controller, or an LSI SAS2008 or SAS2308 controller to use instead with the SAS2 EL1 backplane, plus a set of quiet replacement fans, and one or two SQ PSUs.
As for the 743 / 745 models, bear in mind:
- These are tower cases convertible to 4U rackmount, hence the lower drive density
- The 743 PSU is larger than a regular ATX PSU, with a possibly proprietary mounting
- The 745 uses the same hotswap PSUs as the 8?6 and 8?7 series of chassis' but is harder to find
- They both use the heavy aluminum style of hotswap trays, which are very sturdy, but incompatible with the typical high density Supermicro 3.5" trays, instead they are the type used in the M35TQ 5-in-3 adapter
- Speaking of the Supermicro 5-in-3 adapter, it is a great supplement to the 743 or 745 cases, turning them into a 13-bay tower (or rackmount)
