This is something that I will have to fix, next time around. My new plan is to add a T fitting on the pump.
After you've drained your front rad, you can still drain your reservoir by turning on your pump and forcing the coolant to fill up your front rad. Just keep an eye out to ensure you're not running your pump dry.
If you re-route your top rad to have the inlet & outlets to be on the front side of your case, you can basically tilt your case forward and drain both the top and front rads using gravity when you open your drain valvce. Then turn on your pump to move the coolant to your rads and then drain again.
Make sure to unplug your 24pin ATX power plug from your mobo, jumper your PSU, plug your pump to your PSU so that you're not putting any power to your mobo & components as a safety precaution.
