I'm not sure if you already found a new case yet, but I hope you've recovered from your surgery well enough to try out the AZZA Genesis 9000. Even though it's only a bit heavy, its design is very revolutionary and has a great interior for your hardware. The case itself comes in either black or white for your preference. The room inside is luscious and huge for a full tower. The most unique design for this case is that the motherboard tray can be flipped, which means your cpu will be located on the bottom of the motherboard while your pci-e slots will be on top. This design actually maximizes the cooling the case provides by literally dragging all the heat from the bottom up.
Here's an example of the flipped motherboard design:
If you ever think about giving this case a try, I definitely recommend it.
