Well, I made a little spread sheet and here's what I came up with
1 - $800
5 - $600 With prototyping cost, unfinshed and unanoidized
10 - $400 With prototyping cost, unfinshed and unanoidized
20 - $300 With prototyping cost, unfinshed and unanoidized
30 - $250 With prototyping cost, unfinshed and unanoidized
* I don't have an exact price on everything, so I used some calculations to find rough percentages of the amount of money decreased per tier.
So, I would be laser cutting the tops and sending them to the machine shop. I can only do this for the top of the case and not the base. However, in his quote he has me providing laser cut bases, which is too thick for my laser guy to cut. So prices for the base may be really low.
Unfinished - The machine shop doesn't offer any finishing services. This would mean, unless I find someone else to finish them, they would be going to the anodizing place with a machine finish on nearly all the surfaces
Unanoidzed - I have a rough idea of the cost per rack, but I don't know how many case can fit per rack
