WHen I bought my PowerMac there a couple years ago, I purchased more RAM (I know Apple RAM is expensive, but with my student discount, the prices were more in line with competition) and they offered to install it. I guess that's BTO-ish
 
I don't think you'll find any Apple Store carrying that upgrade in stock.

You're looking at roughly 5 weeks production and shipping delay if you
order the ATI X1900 card.

It is THE card to get if your work demands superior GPU performance,
but get in line..........

It's the hot card to get, so you're stuck waiting if you want it BTO.
