Mobo input questions

[PureAlpha]

Finally getting close to having put my first build together. Confused about a few things so advice would be great!

(A) The mobo has an ATX 24pin power input and an ATX 12V 2x4 power input. Do I need to plug the relevant cables from the PSU into BOTH? (i.e are they the same thing or not - and in that case what does the 12V do?)

(B) There are several 'sys fan' (1 / 2 / Pwr fan) inputs on the mobo. What should plug into these?

(C) Is it OK for any cables to touch the case sides?

Thanks! This is more tiring than I thought!

Great - thanks!

Finally all the hardware has been installed and cable management completed (I hope I'm not forced to rearrange).

I have not burned a W7 RC image DVD yet, but just powered on to see if everything seemed to be working OK.

Seemed to be fine - CPU, PSU and all case fans operating quietly.

The screen displayed:

"PCI Devices Listings

(followed by a list)

Verifying DMI Pool Data ......

AMD Data Change ... Update New Data to DMI!

Update Success

Boot from CD / DVD:

Disk Boot Failure. Insert System Disk And Press Enter."

Does this mean that the system is ready for an OS to be installed, or something else?
