Read this. It will give you a rough estimate how big a power supply you should get. Keep in mind, you may want to add hardware later on so take that into consideration. Make sure the power supply has all the type of connections covered(enough sata, video card, etc. connectors included).

Back to the IOMMU mentioned.

I upgraded to 4gb RAM today and got an error on boot that says something along the lines of BIOS doesn't leave an aperture hole and to enable IOMMU in the BIOS.

I searched the BIOS and couldn't find any reference at all.

So I cleared the error by this:

sudo gedit /boot/grub/menu.lst

Then I added iommu=noaperture to the kernel line

Save

Reboot

Error gone !!!

Hope this helps
