A Sparcserver 1000E will fit three 1.6 drives - two in the lower shelf 
of the drive bay and one above the 5.25" cd-rom.  You'll need 68->50pin 
adapters though.

As Johnathan said a U1 among others will fit at least one of the 1.6" 
drives.  Not too many will accept the thicker drives in multiples.  I 
know also that on some backplanes you can't skip every other drive 
because there is not quite enough space for the top of the 1.6" drive 
to clear the SCA connector above it.  It depends entirely on the drive 
and the system.

If you have a lot of them you might want to find a used JBOD or 
hardware RAID unit that accepts them.  I know the older Compaq tower 
RAID units will fit 68pin 1.6" drives without too much trouble.  You 
might have to buy extra sleds of the right type though but those tend 
to be cheap.  These are the 50-pin ones but the 68-pin ones are usually 
just as cheap:
