I did a bit of research already and didn't come across any filesystems so far that have the following features:
Expandability, Redundancy, and the ability to utilize the full capacity of different disk drive sizes.
Basically, I'd like to get a large chassis that will support 20+ 3.5" drives and just slap what ever I come across in it. The drives could vary from 1TB to 4TB+. I would like to be able to just have 1 volume/partition if possible as well. It's just to store misc. media/scratch drives/temp. Nothing mission critical.
Any idea how I could accomplish this?

zfs sounds like just the thing!
Expect to lose all of your data at any time if a drive fails.
Oh... I missed 'redundancy'.
Put all of your disks into a single LVM VG and then create logical volumes in that pool with LV mirroring enabled. And then test.
But really, @ewwhite is right - take the time and do it right.
