[Cube] Cube power supply failure

Hi John


>2nd proposed solution: Don't expect to drive a big LCD monitor (17"

I did that with my cube in a similar way with the second ADC-DVI-Adapter.
Then I was told by an apple technician that the power for the display 
doesn't come from the DC-Board, but comes parallel directly from the 
"power brick".  Hope, this is right.
The main problems would be: Processor upgrades and graphic-card 
upgrades, not a display (?)

Since that time my situation has changed, I'm using a DVI-Monitor 
with own pwer supply.

How can you use a 400 GB HD intern? With this special driver or partitions?

You can't as far as I know.
