Good quality external enclosure that supports JBOD

[rockinrocker]

I'm looking for a good quality external enclosure that supports a JBOD setup with mismatched drives.

"Quad" interface preferred (firewire 800/400/usb), though esata is optional.

Basically this:

But that doesn't require matched drives.

Any suggestions?

Thanks.
