Congrats on the new system (I am catching up on posts after being gone for a week). Glad to hear everything is working out for you.
One of the complaints I had on my system was also the DVD drive. It was noisy when winding up and using it. However, the GX7 had a device change the week my system was shipped and offered me a free upgrade (to include custom painted). It just arrived and it is silent and smooth.
Take care and again, congrats!
