We have bookcases full of CDs.
We have bookcases full of DVDs.
We would rather have more room, but we don't want to give up the entertainment. So... (you saw this coming, right)
The MythBox gets upgraded from 1.8TB to 3.3TB, a freed-up 500GB drive will store most of the CDs in VBR-extreme, and the remaining terabyte of free space will store the kids' DVDs.
Decent terabyte disks cost $100 each, plus $5 for a temporary USB2 case to aid in transfers.
We get back two shelves of DVD storage, and two complete bookcase units of CDs. The physical media goes to basement storage.
Also, today is beautifully sunny and not too cold. I wish I were healthier.
