Nope, its got onboard Intel graphics, and nowhere to put an add-on 
graphics card. Wouldn't be surprised if there was eventually a product 
refresh that included an onboard nVidia option though... Since the DSH 
is supposed to be Dell's competitor to the Apple Mac Mini, which is now 
decked out with nVidia graphics goodness...

Yeah, you would probably be fine w/a DSH, or even a prior generation 
refurbished Mac Mini.

Sadly, not enough people w/multiple firewire cable boxes to get this one 
figured out proper-like, I'm afraid.

It would force me to use my HD PVR for all cable box stuff, and an IR 
blaster for channel-changing, but I suppose could make do. I suspect 
there will be more ion boards eventually too though.
