The form in your screen capture is $NX_ROOT\bopcfg\www\htmpl\web\employee\home.htmpl and the link you circled is this code:
<PDM_LINK OP="DISPLAY_FORM"
HTMPL="about.htmpl"
class="emp portlet_body_text"
onmouseover="window.status = "About"; return true;"
onmouseout="window.status = window.defaultStatus; return true;">Service Desk contact information and hours of operation</PDM_LINK>
Clicking on the link launches the form $NX_ROOT\bopcfg\www\htmpl\web\employee\about.htmpl
If you want to customize that information then copy that form to $NX_ROOT\site\mods\www\htmpl\web\employee\about.htmpl and make your changes to the copied form. Don't forget to execute a pdm_webcache after you have edited the file.
