Is this hardware too much/ Power drain ?
-
After weighing up the pros and cons i'm still going to go for a P3 system hopefully get one just over 500mhz with 512mb of ram so it got room to grow with my needs, then have the athlon system on standby incase i need to expand in the future.

Yes, the Alix boards work extremely well indeed.
I have an Alix 2C3 bought from linitx.com (your quote seems to be from them also) on a 24Mbit internet connection, and CPU usage is a max of 3% when going full whack at 2.6 megabytes per second down and 280kB/sec up. It could probably handle a good 70Mbit connection just fine, but that's going by my very bad maths only :)
I can confirm that power usage of the Alix 2C3 is 5 watts - I checked with an Aldi "kill-a-watt" style device.

Just out of interest what are the draw backs of running it embedded, as i dont really want to compromise on features, at the moment i'm not bothered about using packages but that may change in the future and i know this device only has 256mb ram.
This device is also alot more money than a PIII machine even though i know i would save money in the long run on power consumption.
Lastly how do you configure the device, it says it has a serial port, not a vga port, how do you configure ??
-
Use the serial console with a null modem cable to set the LAN IP, then do the rest of the config with a web browser.
The only downside to the embedded version is that you can't use packages.

Thanks for the reply
Sorry to sound like a total noob but i have no idea how to do that at all, I thought it would have some sort of VGA interface, is this easy to do, could you possibly tell me how to do this in layman's terms ?
Thanks

For m0n0wall, but it's the same procedure for pfSense: (except the password is pfsense not mono)

Would something like this work,
http://www.mini-itx.com/store/?c=44
I would get the bundle without the HDD so i could put in an 80gb 2.5" drive that i have and also purchase one of the CD rom drives so i could install PFsense ?
I could then put a PCI 10/100 lan card in the pci slot
It would seem to work :)

do you think there would be a problem with the cd rom drive being recognised or are they pretty generic ?

I generally speak and metaphors and usually it serves me well. In the scenario you are worried about the power consumption of this whole setup you have infront of you. The primary component you need to worry about is the CPU. The variation that we all seem to be missing is that although your CPU has capacities to process a certain amount of data at once you have to keep in mind that in most occasions you won't find the CPU running at it's maximum capacity. If the cpu were a bucket and it had to be filled to a certain weight to accomplish what you needed would it matter how big or small it was? The size of the bucket pertains to the capacity of the CPU itself. A P3 1 ghz will have to use as much energy to process the data a P4 at 3.0 ghz, the only difference is how much it can be filled completely. Either processor will use generally the same amount of juice when it sits at nearly idle. Personally I suggest just sticking with what you have, good luck.

Sorry, this simply isn't true.
Your typical old P3 will probably idle around 50w. Peak power draw will be another 25w higher.
Your typical old P4 will probably idle around 100w. Peak power draw will be another 50w higher.For basic firewall use, both will remain just able idle until you start pushing a lot of bandwidth.
It takes a bit of research to build something that uses significantly less power than the P3. Perry already posted some typical power draw numbers back on reply #4.

Thought i would add that i have built my system now anyway, one of my main concerns was power, as I generally don't see the point in wasting in it for wasting sake, just so that i can say well if i ever need to push 500Mbps of traffic i can, because i wont ever have to do that.
I built up the following system;
Intel D945GCLF using a 1.6GHz atom processor
2GB DDR 2 533
On board 10/100 WAN
Intel Pro GT 1000 LAN
Small Cube caseNow it uses 35w of power and sits nicely in the bottom shelf of my computer desk, rather than the probable 200W my main rig was using to power all the fans hardware.
