Steve,
H.P. isn't the only company whose Customer service has gone away. Nearly any of them you call will give you a run around with people who know nothing more than a few words. Now, since I shake so much that I am almost afraid to try getting into the close parts of my computers, I would hire a local repair guy that I know to make any changes for me as I would be shaking and sure as heck slip and bend a bunch of pins of something worse. Buying good cards and building the computer like you want it is the best way if you have steady hands and some patience. Look at the one that Joe built and it would have cost probably 3 times that on the market if he could have found one that had all he wanted. Some brands used to let you specify what you wanted so far as cards and etc, but that seems to have gone by the wayside along with any after market service.
