Pursuing the DIY PVC drive enclosure. I seem to be finding vibrations
from nearby drives killing 'em off (heat is under control) when mounted
densely (as permitted by standard Antec cases).
I realize this is a bit 'ghetto', so there may only be limited interest,
but I'll publish my results.
I plan to build it out of PVC, mounting $6 removeable "mobile" IDE drive
trays (with built in fans) to make swapping easy.
Two questions:
1) Any suggestions for dampening vibrations? I'd like to use those huge
blue rubber grommets, but I can't really find enough anywhere..
2) Anyone know what the limit of the newer "tx2" promise 2-channel ATA
cards is in a given system? I read somewhere the older ones were limited
to 3.. I'm at 3 now.

To the best of my knowledge, the Promise Ultra-100 and Ultra-133 cards
have BIOS limitations, which only allow two cards to be used at the same
time. There may be ways to 'trick' the BIOS to recognize a third card,
but I don't know of any. I have never heard of anyone getting a fourth
card to work.
Now for the good news. The BIOS for the Ultra-100 doesn't know about the
Ultra-133 and vice versa. This means that, as far as the BIOS is
concerned, two Ultra-100 cards and two Ultra-133 cards should work in the
same system. I don't know what the Linux drivers would do in this case,
as I've only done this under Windoze.
I hope this helps.

It works under Linux too. The old 'Ultra100' cards are also
independent of the newer 'tx2' cards so they can be mixed as well.

For the grommets (black only), try an auto parts store. These would be
best when used with a shoulder screw. Both of these components are used
in the Antec Sonata case, but aren't on their web page. You might be able
to call them, and order some.
