I am considering buying broken macbook pro laptops to fix up and give away to underprivileged children and youth as apart of a charity. I have some mac knowledge and come from a technical background. I see many macbooks for sale on ebay. All price levels. Is there certain repairs I should stay away from? I see flashing hard drive I am sure is a easy fix, but spill damage is more complex and maybe not worth it. Let me know. I tried reaching out to some fix it yourself sites. But they seemed to be jerks about sharing their info, so I am reaching out here to the friendly people.
