You don't need any Service Packs to Install the Windows 7 o/s. At this stage, SP1 for Windows 7 Is In the Beta stage.
I do recommend a clean format and Install the latest drivers via the Manucturer's website afterwards.

Here's a Torrent download for Windows 7 Ultimate, In both the x86 and 64 Bit architectures: http://www.h33t.com/details.php?id=961a0...ndows+%2B7

If you require activation, use the new Windows Loader v1.9 by Daz here: http://www.h33t.com/details.php?id=0f8eb...+%2Bloader

Thanks for the links, downloading now.

So do I need to use a specific type of DVD to burn windows 7 onto? Or will any kind do?

You're most welcome mate.
As long as the DVD can hold the capacity of the file (which In this case It can), you can use any single layer disc, being 4.7GB In the DVD-R or DVD+R/RW formats.

Now because the file Is In Iso format, burn It as Is and boot from it.
I recommend you use this freeware burning tool: http://imgburn.en.softonic.com/
