    Default Low Power PCs

    Hi All

    Have had my Eee Box order cancelled, and am now free to purchase a low power unit to run my cortex system has anyone come across one or is using one that can advise.

    thanks

    Maybe it will help if we list our Cortex servers and measured power with a plugin meter?

    VIA EN-15000 Mini-ITX Mobo and Matrox 70GB HDD = 28W

    My Dell latitude D600 (centrino 1.7G) consumes 19W with screen off, 26W including screen - another advantage is it has battery backup. Still - no expansion for the telephony card I bought ages ago. I am hanging on for an Atom with low power chipset, serial port plus at least 1 PCI ... its been a long wait for something better than the laptop as sadly PC cards with centrino chips have always been very expensive cf VIA mini-itx etc.

    For Mini-ITX probably easiest and best to go with VIA themselves or Jetway. Have a look a Linitx or Mini-ITX websites. If you have a single machine then you probably want it to be a bit more powerful and that over-rides the power consumption, consider the EN or SN boards from VIA.

    If you just want a dedicated PC for HA then Cortex has very low requirements so you could look at something like the Jetway J7F2 1.2Ghz Eden CN700 Mainboard which is Fanless and consumes 7W plus chipset and HDD means like power consumption around 15W (educated guess rather than my own measurement)

    Just to clarify Mini-ITX is a form factor so you can have Mini-ITX motherboards with an Intel Atom or AMD Geode as well as the more normal VIA CPU's.

    power requirement (in both senses) would go up a bit if including a capture card & CCTV in the HA scheme, of course ... as part of presence sensing, as well as for identification & baby-sitting ... we certainly chose our MiniITX board to cope with this ...

    I was tempted by the a Jetway board like this last summer (may have been this one). How do these processors compare with a centrino in terms of grunt/Ghz? Is there a SPECint rating for PCs?
    not sure what you mean by single machine, but I'm looking to build a machine for Cortex primarily and low power is key as its running 24-7. In a perfect world it would be power-stepping so that as and when I get around to adding a CCTV camera or two and activate them the same machine will run with a bit more juice and soak up the load. The Centrino seems very good at this sort of thing, but has moved dual core and higher power (juice).
    I've monitored the CPU on my machine and with Cortex its <~10% on my current machine which is great.
    The marginal improvement in juice of the Jetway plus my perception it will be lower grunt, doesn't make the case for me to experiment - still saving for a house full of DFPs :-)
    Thanks

    a VIA EK10000G & as much memory as it would take + IVC-200G capture card

    (took a moment to find it - had to go find what box it's still in - daren't bring it out & put it together 'til we've finished plastering & screeding - too much fine dust ! - and that's waiting on the thermometer coming up from its current miserable levels ... busy bringing up to date & finalising our plumbing & heating & electrical infrastructure design at the moment, big job)

    hi
    Thanks for the response have being looking at www.mini-itx.com site, and they do a starter bundle using a 1.6ghz atom chip starting from 149 depending on hard drive, any advice welcome as to the suitability to run HA only
