Very cool post. If Jeff Geerling is reading this, I wouldn't mind watching a video on each of these ;)
Check out saveitforparts on youtube, he does lots of this stuff.
Gabe just quit his dayjob to go full-time on SaveItForParts, so hopefully we'll be seeing even more cool stuff in the near future. Me personally, I'm hoping for a collab between him and Jeff. They've had some interaction already (Jeff donated Gabe a spare computer he had lying around) so maybe... That would be epic if it did happen.
