They already said they're running pretty tight margins on boards, and are looking to make more profit on the cases, and especially on complete turnkey mining units ready to run with PSU, case, etc all together with the board.

For those of us who already have a PSU or want to get one of our own, maybe do our own case or fabricate some mounting hardware to mount in something like a rack mount case, this is perfect.
The case they're offering looks nice, and if I had gotten into bitcoin sooner and had a ton of BTC laying around I'd go for it.  But I don't really *need* a nice fancy case and psu and fans and all that.  I have tons of spare parts laying around so having the option to save money is nice

Why is the case just by itself cost $1200.00?

We have sample chips, a few K16 boards, and all the components. We will assemble a board for testing by this weekend.

There are 2 possible scenarios:

1. The chips arrive unmarked/unsorted leaving me no choice but to send chips 100% randomly. Since only 5% are class-D a random selection should leave everyone with well over an average of 4 gh/s in any 5 chip batch.
2. If the chips arrive marked with quality/class I will simply send owners as close to the split of chips qualiy provided by BFL in the product statement.
