Update: After doing a rough count of inventory, profit margins for helping me rid all of it can range from several hundred dollars to one thousand dollars. Obviously an exact profit number depends on the exact number of cases as well as the price point set. But after shipping costs are deducted, these figures came from an estimated price point that is so extremely low it's practically giving them away.
Certainly a nice chunk of spending BTC for never physically needing to touch a product!
I am an Amazon reseller; my biggest question would be whether or not you could market these as having ANY other uses?
Well currently I am using one myself for my non mining desktop computer. Since it's open frame and my room gets quite hot, it gets maximum air flow naturally which helps tremendously, so above all it's a solid computer case (as solid as a case goes in the open frame department).
I suppose they could be used as some type of desk / counter with shelves every 6 - 9" or so, but I'd have to double check that to be sure it doesn't look too tacky (selling it as one thing when it clearly was designed for something else). Though using the CNC router system for material cutting, if something like a computer desk or furniture is something very profitable to sell, then it's simple enough to design a product specifically for that. I get anal about quality so it would just feel wrong doing anything but creating a new design from scratch based on whatever product we'd market. So in the end, out side of this being a computer case, I can't think of any other uses for these where I wouldn't have that feeling that I could have produced a much better product if that was my intention from the get go.
