The killer for RAM is the number of concurrent processes running to handle
incoming requests. Our clients that handle hundreds of thousands to
millions of requests per day typically want to handle peaks of hundreds of
concurrent connections. If each one take 20MB of RAM, which isn't unheard
of for dynamic applications, you're talking 4GB of RAM just for handling
those requests. The big event being when a robot or spider hits the site.
That's one of the biggest issues we're running up against on the python.org

Yeah, I've had good luck with them, though recently a batch or two from one
vendor had a high number of failures. Since then, we've had none,
and before then none.

I've had good luck with Intel motherboards, but most of my experience has
been with Supermicro. They rock. Personal preference here, but I won't
use AMD's CPUs. I'd like to, but usually it means using other chipsets on
the board, which tend to have nowhere near as good support as the Intel
>I _think_ you'll pay a big premium for a dual-socket motherboard.
the biggest problem is that you're not going to get a P4 board that you're
going to be able to upgrade to dual CPUs most likely. You *MAY* be able to
do dual cores, but the Pentium Ds are getting to be quite short in supply
now, so you'd have to get a board that can support P4 and Core Duo, which
may be scarce in "server" quality boards.
I'd recommend you get just a P4 board and don't worry about the future.
When you want to upgrade, get a new board and CPU, whatever fits together
then. Trying to predict the future as far as computer hardware purchases
is rarely a benefit.

I've been happy with the Antec cases I've bought, but they're all tower.
No idea about what they have in rackmount.
