We all know how painful it is to do a new installation and keep applying the latest updates. Or even worse, trying to install MOSS 2007 on Windows Server 2008. Well Microsoft is kind enough to distribute a version of MOSS 2007 with SP1 integrated. You can get both x64 and x86 versions from the Microsoft Download Center. Here are the links:

MOSS 2007 with SP1 x86

MOSS 2007 with SP1 x64

Do not be alarmed by the word "Trial" as these distributions also accept valid product keys for full functionality.
