thx pyrat. yeah you can - just don't leave it too long otherwise the component batches i order might be too small, you'd have to wait for another production run - just have to see how it goes.
Ah, I see it's now called "pre-order" not "pledge", and the number of requested items is no longer shown. But it's more or less the same.
It also seems some items have changed the shipping date, curiously, some cards ship march 2017 and some april, depending on the OS, although
the hardware is the same.
Btw, $171000 (114%) now. It seems there is margin even if some people canceled or some payments didn't work.
