Enterprise hardware is different than consumer hardware.
Often 10 times more expensive.

Sounds not worth it to me. There are now consumer RAID systems, which
often allow any (so long as all are identical) drives to be used in
them. They'll be reliable enough. Maybe you'll have to replace a drive
in the array a bit more often, but if those drives are a *lot* cheaper
the savings will add up and add up.
This is why IBM and Sun are in talks to possibly merge; the high-end
hardware market is shrinking, being attacked from below by commodity
microprocessors and drives and similar hardware, cheap and parallelizable.
Both (or the result of any merger) will eventually have to shift to a
more service-oriented business, supporting hardware and software and
providing cloud computing services. Give away the software, sell cheap
hardware at thin margins (or even at a loss), and sell lucrative support
contracts and cloud services.
The evolution towards this strategy is dictated by the price pressures
generated by Moore's Law, which makes any given potency of hardware
become cheap given enough time, and also drives the per-copy cost of
software all the way to zero with cheap storage media and bandwidth.
It's no coincidence the rise of the Internet was accompanied by the
collapse of software and music and other prices. (1990 -- cheapest
full-featured office suite, $159 or so; 2009, $0 (OpenOffice.org); 1990
-- cheapest you could get a song about $8 if available as a single, $16
if not; 2009, $0.99 at iTunes, and $0 if the artist gives it away (or
you pirate it). And a lot are giving it away -- Radiohead and Trent
Reznor recently made headlines doing so, and by actually making money by
doing so.)
