I think that there should be more photos of the other color on the Kickstarter. I'd say that a good number of would-be backers are on the fence simply because there's only 1 photo of the silver case and another close-up photo of the 2 colors that seems to showcase the ash more.
Someone new to the campaign might like the idea, but won't back until he/she has fully seen the other color. Also the ash color does not show off the spine mounting holes, vents, the panel gaps between a top hat and the case as well as a lighter color will. With some folks itching and complaining about an extra mm or two in case width would definitely like to see the tiny details.
And please don't use the instagram photos with filters and color corrections on it. The simple limestone color case showcased on a desk next to a monitor like the original ghost s1 was will would do. Like these:
We get that there's some favoritism with the ash black. But if you offer more than one color, be sure to show off both colors well. You'll sell more products when customers can visualize a product that isn't physically in front of them. A lot of people may have Audioengine or Kanto branded speakers in a white or grey that they would like to match.
Remember if there's someone that's obsessive about the flush look of case power button or not seeing usb ports on the front panel, they will be obsessive about the way this product fits in with what they already have on their desk. New monitors, higher end audio equipment, custom mechanical keyboards, etc.
