Interesting that you say selling things isn't skilled work - when you need to know how to get payments, where to list, how best to list, how to deal with purchasers, what the best way to take payment is, figuring out shipping and packaging. These things are skills, and once you know them, sure, it's easy... but you still had to learn those skills.
While I think it's less time overall to resell than build, for sure, I also think you're stacking the deck by handwaving away the time and skills involved in reselling.
It isn’t skilled work and it’s not taking time away from my actual work. It’s hard to put a price sticker on, just like I don’t calculate how much money I waste by going to a movie.
There is another reason why I didn’t mention the time it takes for resale. From reading the article I got the impression that OP didn’t count the time it took to research the various components of his Hackintosh, the time it took to look them up and order them, and dealing with the delivery. I think those activities easily take longer than reselling a recent Mac.
