You will need some minimal air flow, especially in a rack. I think the Supermicros are a bit on the "too low" side. The axial fan one (haven't seen it yet) might do better. > I'll probably spring for a SSD as suggested. Do I need 4 GB memory or So far, Transcend SLC SSD and Intel 2nd gen MLC SSD.

It's not that it's going to increase the price considerably, so it's a no-brainer. > * A minibox.com fanless enclosure with external 80 watt ps runs $70 > (silver) and the MB is $190 = $265 > > versus > > * A supermicro atom server from newegg for $360.

The ps - 80 watts is probably Fanless box might be ok if it's got enough surface and is mounted so that it can be passively cooled by convection. > the max it can handle.

Haven't used a Kill-A-Watt(equivalent) on it, though, so that's a conjecture. -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://www.ativel.com http://postbiota.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] Commercial support available - https://portal.pfsense.org
