Gaming or work?

If gaming, Thunderbolt enclosures seem to be the best bet, but the cost (as well as hardware support) is so prohibitive that you might as well build a dedicated rig.

As for work, I'll re-look at this and post later.

Will have to check around more but it's NOT going to be easy... Your Elitebook 8470p is a dandy of a unit (I had one!) but your only hope lies in its Expresscard 54 slot to an external PCIe16 slot (running around 1-4x speed, but that's not bad considering.)

I don't think anyone truly made a full kit containing external box, PSU and connector card - though it had been propositioned.

This is STILL easier than finding a compatible MXM module and getting it installed.
