Go to Setup > Customize > Home Page > Home Page Components.
Choose the HTML component type, give it a name (e.g. Home Page Dashboard), designate it as a wide component, check the "Show as HTML" checkbox, and copy-paste the following code in the text area:
<iframe src="/01Z?isdtp=mn" width="100%" height="500"></iframe>
Click save without unchecking the Show as HTML box. Next, go to Setup > Customize > Home Page Layouts, create or edit a layout, add the component to your layout, and save. You'll need to assign the layout to the profiles that should use the new view.
Edit: As a side effect, you can also run reports from your home page.
