Yeah, they're a bit less cut-down than the Atoms, but still not "real"

Note, also, that even if you go with the Tom's design, assuming you can
fit a discrete nvidia video card into it, it will not significantly
raise the idle mode power draw. A good GT430 tends to have an idle
power draw around 7-9W (though this can vary from card to card depending
on vendor, etc.) and a good GT220 has an idle power draw around 9-12W or so.
Generally, 12W run 24/7/52 (24 hours/day, 7 days/week, 52
weeks/year--yeah, I'm trying to change the "broken" saying of 24/7/365)
will cost about $12.50 for the year assuming a US national average price
for electricity of about $0.12/kWh. Best way to save electricity/money,
though, is to shut off whatever system you get when you're not using it.
And, if you get a passively-cooled video card, it's not going to add
additional noise (unless you have insufficient airflow in your case and
it causes the case/CPU fan to run faster or something).
