As for airflow being for amateurs, that "amateur" class includes the State Farm Insurance and the Department of Defense, which run the number one and number two largest networks in the world--and they do air cooling.
I've been building business machines myself since 1988. I'd say "high end gaming machines" may be nifty, but they are
for amateurs, by definition not for people who are running a day-to-day business with them.
The OP wanted an external drive for backup, and I simply offered a suggestion that works for me and plenty of other people. If you think that everyone should be using forced-induction tabletop RAID enclosures for occasional backup, then that's your opinion and you're entitled to it, but I don't quite understand why you feel it necessary to shoot down everyone else's. Plenty of people have used enclosed notebook drives (both prebuilt and self-built) as backup, and they work just fine.
I was using the term "amateur" figuratively, but with all due respect, your examples of State Farm and the Dept of Defense are not relevant - their systems are prioritized on cost effectiveness, not absolute performance. Air cooling is cost effective, and I'm not knocking it for the average home or business user. But for absolute effectiveness? It doesn't touch liquid cooling, which is almost required at the level of overclocking today's enthusiasts run their top-end gaming rigs, which you dismiss so offhandedly. To use an even more extreme example, look up what kind of cooling the Cray XT5 Jaguar (as of Nov 2009, the world's fastest supercomputer) uses. It ain't air; in fact, Cray calls air cooling a "technology of yesterday" (lol).
Again, I'm not knocking air cooling; I'm merely pointing out that business machines are merely one out of many categories of computers, and there are at least several that are far more demanding in terms of performance and HVAC requirements. To get back on topic, in my experience as a family photographer who backs up about 250GB of photos and movies about once a month, my 500GB 2.5" drive in an aluminum pocket-sized enclosure does just fine, and has never gone much beyond room temperature even after a full backup. Anyway, enough on this topic from me. I wanted to offer an honest suggestion to the OP, not get into a debate or hijack the thread.
