This is a great idea.
I just added the ability to upload HTML content into the ETP package on this site, so we can setup an ETP section, or just upload your case studies into file storage. There is already a folder for marketing materials: https://openacs.org/storage/index?folder_id=95336&n_past_days=99999
Then we can just setup a page of links to the file storage items.
That way any registered user can upload a case study.
