I went out and bought a new NVIDIA 9800GT video card. Seti are currently testing a GPU application. I was planning on putting it into Qui Gon Jinn (one of the 5 ACER quad core machines).
I shut it down yesterday, opened it up to check the power connectors as the video card requires a seperate power cable. Qui Gon has SATA power connectors and the supplied adaptor cable is for molex connectors. So I closed it up without doing anything to it, plugged it in and now it won't power up at all. I have booked a service call with ACER. They have already failed their own benchmark of contacting me within 4 business hours.
