It's interesting that the vendor (ICC) advertises this as a 12-disk box,
yet it's only an 8-disk chassis. Additionally, the PSUs are 720W, not
800W, so I'm not sure why they claim that either.
The chassis in question is almost certainly a Supermicro SC825TQ-R720UB,
by the way:
The picture doesn't show the front bezel serial/USB ports mounted, but
they're visible on the SuperServer 6026T-URF (which is probably what ICC
is selling anyway, pre-populated with CPUs, RAM, etc.):

It would be even better to simply ask them what exact Supermicro
hardware (specifically, model numbers) they're using to build these
systems. You can see Supermicro mentioned in the <title> of their site,
so that's definitely what they're using, even down to the controller
card offerings (some of which (Marvell) are known to behave oddly on
FreeBSD (yes there are success stories, but there are also follow-up
horror stories) -- consider yourself warned).
