SATA cable just hanging outside of PC?

I have a 20-bay Norco case with proprietary drive sleds.

Periodically, I want to remove a drive, take it over to my 24-7 PC, and
run tests on the drive.

I have a slide-in SATA bay on the 24-7 PC, but unscrewing the 4 little
screws that hold the drive in the NORCO sled every time is getting old.

I am thinking maybe just a long SATA + Power cable hanging out of the
d24-7 PC's case. Something like this:
http://www.satacables.com/micro_sata_cables.html in the 36" flavor.

Then I just plug it into drive's connectors without removing it from the
sled.

Does anybody see anything wrong with this idea? I'm thinking something
around static discharges and the exposed SATA connector.
