OS 10.5 - How do I Make "Macintosh HD" show full sidebar

I'm not sure if this is possible but at the moment when i click on Macintosh HD on my desktop it opens with just a basic sidebar with Macintosh HD, Network and any devices i have plugged in. However I prefer the way folders look when they are opened with finder (with the full sidebar including "Today", "Yesterday" and "Past week" etc.

So is it possible to have it so that clicking Macintosh opens a folder with this appearance?

Thanks in advance
