Another +1 for the Rosewill 12-bay/15-bay cases. If you're going to run this server anywhere near you, stay away from server cases like supermicro, dell, etc. since you will suffer hearing loss if you're around them for long periods of time. If you plan on using ZFS, make sure to take into account for the overhead and parity drives. For example, I have 12x 16TB (192TB raw) drives in raidzfs2, including overhead and parity I only have ~125TiB usable.
