Why would you recommend the V3 to someone who only has FW400 and USB?
Neither one would be my first choice, but the v2 uses obsolete IDE drives
while the v3 uses SATA. If I cared about the form factor or the USB hub
features, I'd go with the v3.
OTOH, they're both plastic, noisy, and cost much more than good fanless
aluminum enclosures.
