Hi,

Shameless plug for a trademe auction of mine....

Asus V9520-X/TD/128M/A 

AGP with DVI output.  128MB & Passive Heatsink.
Low power for sure, but that's kinda ok if you just want basic ability to output to hdmi.
Also being small it's hopefully ok to work with older power supplies etc with out too much drain.

Also there's a cell phone of my brothers on there too!
