Best board that matches those features is the Code with Green switches (http://www.wasdkeyboards.com/index.php/products/code-keyboard/code-104-key-mechanical-keyboard-mx-green.html). It has White backlighting, full size (with standard layout), clicky switches. It doesn't have macros, but you can use AHK for those (if you actually really need them).
If you explain what you use the macros for we can perhaps advise you further (most games allow you to program macros in-game, for instance). I would stay away from the Corsair K95 since it has a non-standard bottom row, so you will not be able to put higher quality keycaps on it.
I've only used Browns and I like their weight so maybe Greens'd be too heavy
I use MS Excel and Word a lot, so I'd use them for Alt shortcuts such as Alt+H+U+Tab+Enter+(Shift+Enter)
I've never heard about AHK - I'll have a look in deciding whether I can use it for anything
Thanks
I see. Well, there's the CMStorm Trigger Z which comes with Blues, but it has
blue backlighting and 5 dedicated macro keys.
You mentioned the Mech as well and that is an option, although it's big and bulky and has non-standard layout.
If you want white backlit fullsize with standard layout and Blues, there are a few options if you don't mind using AHK to manage your macros:
1. Ducky Shine 3 white LED, MX Blues:

1. Razer Chroma
The Corsair RGB boards with Blues have been discontinued as you mentioned.
In most cases, moving your hand across to push macro buttons is less efficient than pressing the Alt combo if you only need a single key in combination with Alt. For more complex combos you can assign them to simpler ones using AHK, so most of the time macro keys are a false economy.
