If you had enough money and don't mind that it is pricy + can accept the BigAss enter(with small backspace), then by all mean go ahead.

If you want purer mechanical kb experience, try Filco or Ducky. Though they are around the same, all acceptable.

Erm, you want a black or white case keyboard?

You can always go either one and purchase keycaps of another color.

For example, go for rosewill ivory(white) color and then purchase black PBT dyesub keycaps from kaiserreich.

White on White will be very subtle and probably also difficult to see at night due to lack of contrast. Working on getting white backlight keyboards in. OEM by same factory as Razer. But it's not in a classic form factor albeit more "gaming-like"

if you want white LED board, go for Ducky Shine. it comes with various LED colour, white is one of them.

if no LED, Rosewill Ivory looks superbly great.
