Internal DOCSIS modem?

[out there]

I have only read about the Broadcom bcm93300i and Zoom 5001, but I haven't been able to find a place to buy one (or any internal DOCSIS modem).

Can anyone offer some information about these models, or this type of device? Upsides, downsides, anything?

Why would you want this?

None of these will work with current standards today.

They are all DOCSIS 1.0 and 1.1... Most cable companies use 2.0 and 3.0 today.

I suppose I just hadn't done any research that is specific to the differences between 1.1 and 3. Naively, I would have assumed that they're backwards compatible with slightly reduced performance.
