Well, that's not the user experience I was hoping for...
You select to add a "Case", choose from the list by hitting "details", and then you will see an add to configuration button.
Add the case. Rinse and repeat for the other items required (only the first page, case, monitor, keyboard, mouse).
click continue on the next two "step" pages at the bottom.
On summary page, click "add to cart".
Then you'll see what I'm saying. =/
I'd prefer an ajax configurator, but haven't seen a mod for it
