My $35 5 nic atom d525 build with pictures
-
I didn't have a case included because I haven't found one yet. I'm still looking for a 1u case iwth psu for under $50. It'll pop up sooner or later, my rack isn't ready yet anyway.
Since it is only a router, and each port has indepedent traffic, it's litterally impossible to saturate the pci bus without 500/500 internet going full speed. The bandwidth is total 132MB/sec. THe multiple ports won't be acting as a switch connected to different computers, so doing machine to machine transfer will never go in one port and out the other. They're simply going to be 4 gateways on the same network, and machines will push traffic over them based on their settings.
And I'm only 30, but i was an electrical engineer in the military, and worked at radio shack before it sucked, so I know my way around circuit boards :)
And there's still 2 of these cpu/mobo combo's on ebay for $25, but now have shipping charges. Still is pretty cheap.
This is hte rack it'll be routing. there's 15 vm's on a 5 server cluster.

Nice. :)
I'd still be interested in any figures you could generate if you have chance to run a test before it goes into production.
Still hard to beat a Firebox for minimum cost if you want it rack mount. About the same perfomance as your Atom board but can be upgraded. The new multithread pf in 2.2 will probably make the Atom perform better though. Atom uses less power too.

I looked for months for something like a firebox, but found nothing. Now I gotta go and buy one of those and play with it…

Your post gave me a great idea! I started looking at the internals of those machines, they use a standard 20+4pin psu it looks like! So I could gut a $25 with free shipping firebox and put my atom mobo system in and stick the pci card on the pci port, then I'd have a $25 1u case with psu for super cheap.

Yep, you could do that. I don't know if you'd get the NICs to line up with front panel. The LCD+keys uses the parallel port header. The usually cheaper X-Core models (X500, X700, X1000, X2500) do NOT use a standard PSU so make sure you get the right one if you go this route. ;)

Congratulations. I never realised that PCI-X is backwards compatible that way. Really, could I take any quad port nic which is 64-bit PCI-X and use it like that?

No. A lot of cards are SUN or specialty production and not compatible with windows, let alone pfsense. Your best bet is to stick with the intel pro/1000 chipset. HP's and intel's use hte intel chipset. Right now the cheapest I see is $25+8 s&h.
PCI-X runs in pci, but be weary of hte notches. Front notch is 3.3v, rear notch is 5v, both notches is universal.
Here's a better search:
http://www.ebay.com/sch/i.html?_odkw=quad+ethernet+pci&_sop=15&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.Xquad+ethernet+pci+-sun&_nkw=quad+ethernet+pci+-sun&_sacat=0You still have to scan through to get ones that will work though. Tundra chips also work.

I'm frugal is most of my life, but when it comes to stuff like a firewall that I don't want to mess around with, I go all out. i350-T2 NIC, complete overkill, but that's how I roll.
I love how you knew about the double notch thing and all. I applaud your hardware skills!

In reference to modifying a PCI-X card, that is a tricky route to take. The notch placement is what keys the card between 5V and 3.3V operation. In general, standard PCI slots are 5V while PCI-X slots are 3.3V (though the opposites are possible as well). The card in the OP was originally keyed as a 3.3V only card but was modified for 5V (there are universal keyed cards). That card had no pins in the location where the 5V notch would be so it was a good candidate for modification but if the card has pins in that location, I would not attempt it as you would either damage the card from the modification or by giving it different voltage than it expects (or is capable of handling).

While very possible, I gave up on this. The price of buying a case/psu is to inefficient vs just buying something, considering I'm fairly sure that my needs will completely blow this little atom out of the water. I've decided to go dual e5410 xeons with 8gb ram.
But i'll leave this here just so people know they can do it if they want. Multiple vpn's on hte router, content filtering, and hundreds of users, eh it's a bit much.
Switch config time for vlans and LAGs.
