Thks for the reply, Geek....I kind of figured as much. I just recalled seeing that enclosures for the larger drives often came with fans. Just about any of them will do, for sure. And also, thks Trudy for your thought.....it's really just kind of a "thing" for me to fool around with this stuff. Most of the time, I'll weight the cost vs benefit of doing it with parts or buying something new and go with the easier choice as you suggested. Kind of why I like to build AR-15's from scratch, too!
Happy New Year!!
