Well, the PV I'm planning to put this on isn't backed up at all.  It's
torrent data.  If it is lost, hopefully I can get it back again.  Still,
I don't want to lose any drive or data if I can help it.  It's why I
always get cases that have good cooling.  My old Cooler Master HAF-932
had excellent hard drive cooling for the ones mounted on the bottom. 
The 5-1/4 bays not so much.  While running a bit warmer, it still cooled
good even when filled up.  My new Fractal Design Define 7 XL has even
better cooling in a way.  The hard drives are not as close to the fans
but it cools all mechanical drives.  Anyway, it was something new to me
and I was curious as to what it does.  Reading other replies, it sounds
like it is OK but as with anything, there can be issues.

1/3rd of my garden is for people.  Kale, collards, turnip and mustard
greens.  That is inside a electric fence to keep the deer out.  The open
part outside the fence is a mix of oats, clover and such.  I just grow
it to keep the soil erosion down, improve the organic matter and let the
deer have something to munch on, besides what is inside the fence.  I
did have to add another spool of fence tape tho.  Dang deer got in but
had trouble leaving.  He tore up my fence a bit.  I got the wires closer
together now so he won't be getting in again.  Funny thing, bucks tend
to tear up fences.  Does rarely do.  It's the antlers.  They get hung up
and the shocks makes a deer want to be somewhere else.  I can't blame
him tho.  Those shocks hurt, bad.  Several of them can easily kill a
deer sized animal, even a cow or horse. 

Time for my weekly Doctor visit.  Reply to others later on.
