[SunRescue] An intriguing idea...

Tue Apr 11 16:56:57 CDT 2000

Do you have any of the drive "sleds" for the 911 box?

I've got the box half filled at work and would like to add a couple of
drives to it but I don't have a second set of sleds for it.

No, 811 is the single height 5.25" drive bay box.  You're thinking of the
911, which I've got a stack of at the moment.  You've got me thinking,
though, so I'll have to go home and check the dimensions tonight to see what
might be doable.
