The power supplies sold with cases are generally pretty poor, unless it's an
expensive well-known maker case. As another person mentioned, I'd also suggest
replacing no-name PSUs with good quality units, preferably with ay least an

The Revo is indeed a nice machine, for a frontend, but I wouldn't use it for a
backend. The internal HDD is a 2.5" laptop type, not noted for great
performance, but you can netboot the machine and not need any hard drive at
all. I wouldn't put a 1TB in it (not even sure if you can get that capacity in
a 2.5" form factor), as I wouldn't use the Revo for a B/E, or for storage.
If you really want a larger drive you could use the E-Sata port, but you
really only need a smallish drive for the OS and the frontend code.
If you do use it as a BE/FE combo I'd use a separate drive for the OS and the
database and something else (probably external) for video storage.

They do, and quite well, but only as frontends, as I said.
Personally I'd go with a server class machine for running the backend and
video storage. That's what I do, server machines are designed for 24/7
operation. They do tend to be loud, but if installed in a garage or basement
who cares? Used server class machines can be had relatively cheaply these
days, a 4U rackmount machine can hold a lot of drives for a RAID array.
