One possible MAJOR flaw with tiny systems, is that the built-in cooling fan has to be small to fit the small case.
And small fans are VERY NOISY!!! (heh, can you tell I had a small system with a tiny fan here once?
)
So, in a shop, church hall, or office building, one may never hear the noise. But in a small, otherwise quiet, room at home.. things could be very different.
Now this particular Dell may be quieter than most small things with fans, but it's something to really try and figure out in advance.
Larger fans, running slowly, are more effective and a lot quieter than most small fans I've had here.
Cheers
