So if someone wants to have both panels (vented + vented window) , you must at the basic configuration to choose vented and add as a separate part the vented window (+40$)?
And if you buy it as a separate part do you still have the 20$ off?
On the configuration pick left side vented with window, and select right side vented.
You do not need to add the window under the parts tab.
$20 applied to new cases or to buying just the window + vented panel.
