5 points for style
Faster is better !
I extended the power from inside the case and connected the eSATA drive to one of the SATA ports on the mother board. Not pretty but it's major fast. 3 Gb/s transfer speed. Seagate 450 Gig PMR drive used as storage for "stuff". I can save a 1 Gig movie in about 20 seconds. Fan and fan mount from spare junk.
I have an external case but it had no cooling fan.
