actually, I am aware of the grounding issue. I currently have two
separate single disk external enclosures connected via esata and an
esata adapter on a PCI back cover plate right now.
so you need to add one or two 2 or 4 way esata adapters to the icy box,
too, and use esata cables.
5 seems a reasonable max.

I thought that might be what you were talking about, but I wanted to be
sure.
Shelf, fix icy box and PS, short pins by clips-and-wire and add som isolation
for safe op?
Can you suggest a cheap and commonly available sata pci card that can work
in an X7BSi mb based computer?
This has been a long thread, that has confused me a bit. Can you remind us
what you're trying to do?
Since I'm currently doing this, and learned the hard way, I'd like to inform
you:
Suppose you have a computer chassis, with enough internal SATA ports, but not
enough internal space to hold drives. So you want to add external drives. So
you dangle a SATA cable out the computer, and you want to power an external
drive using an external ATX power supply. (This is what I did).
Then you short the pins, as Saso suggested, in order to get the ATX power
supply to turn on. BUT you MUST connect the external ATX ground to the
computer ground. Simply sharing the common ground pin on your wall outlet
isn't enough. (I fried two of my hard drives. That's how I learned the hard
way.) The easiest way is to simply take out one of the screws of the ATX power
supply, put an eyelet tipped wire there (with the screw put back in obviously)
and connect the other end of the wire to the computer chassis. Just wire the
two chassis' together.
If you look at an ESATA cable, it's exactly the same as the SATA cable, except
that it includes an external ground connector. If you buy something like a
Sans Digital (I like the brand) ESATA external enclosure connected via ESATA,
then the ESATA cable guarantees the external chassis and internal chassis will
share the common ground.
If all you want to add is a couple (up to maybe 4) drives, then SATA works
fine. Beyond that point, SAS becomes the obvious better solution. Because in
SATA, you have to run a separate cable for every drive. While in SAS, you get
24 Gbit in a single cable. (4 channels of shared 6Gbit)
