Hello everyone. After many moons of searching the various markets and vendors across the webs I have come to the realization that nothing is out there for me. So I decided to make my own but now I need help since I want to be as well informed as possible. The closest keyboards that I have found that have most of the things im looking for are the Corsair K95 RGB Blue Switches, and the G.SKILL RIPJAWS KM780R RGB. The one that is "Perfect" for me is the K95 but the blue switch model has become a unicorn from what it seems. The G. SKILL one doesn't have enough G keys for me.
To make it easier to get the help I need here are my must haves FULL Keyboard (Nothing Less) Dedicated Media Keys (Volume Knob Prefered) Programmable Keys 6+ (12 or 16 Perfect) Blue Switches (Green Switches Prefered) Or Something Similiar RGB Programmable Keys (Can settle for just Blue Leds)
Those are my must have features anything else are just cherries on top anything less depends of what it is and if I find it worth it.
From the research I have made I created some Keyboard layouts that I feel good with.

That's the general layout I want with the programmable keys on either left before the alpha keys or on the right after the numpad. From here is where I ask for the help needed to complete the job. I found some decent CAD builder sites that give me the blueprint I need for the case and switch layer. But I want to know if there is a better method that wont involve spending hundreds on a case. Also is it possible to find a single PCB that will do the job or if I would need to get multiple or is hand wiring the only way to get it done. Plus If I could somehow add a knob to control the volume.
Thank you all in advance for the help I hope you can help me fulfill my dream board.

Sounds like you have very specific needs. Other than the K95, I can't think of any boards off the top of my head with all of those features.

Why not find a standard full-size board that you like and get a B.pad or Gonpad to place on the left side of the keyboard? Those are fully programmable so you could use them as a macro pad. You could even build one with a 6x4 grid of 1u keys like so.

Mmmm, macrokeys...
I've been waiting for a drop of the GH-122 (https://geekhack.org/index.php?topic=88063.0;topicseen) for a while.

The designer has been off-line for a while, but I'm still  quite hopeful. Supports up to about 150 keys, many configurations.
About 50 macro keys (or populate it with less). There's 40 in the 2 function key rows, drop a few pairs for clearer
separations of your intended groupings.

Everything fully programmable. You'll need space on your desktop for it. ;-)

As far as inexpensive cases go, a number of people here have done laser cut acrylic. Takes a few layers, but workable. Good for prototyping.

'Luck!

Just use 2 keyboards .. put an extra board to the left and customize it to whatever keys you need.

Designing/building a keyboard from scratch is a large, expensive, and time-consuming endeavor.

If you can make room for a 122 layout you might find that it gives you a lot of options, and many/most of them have clicky switches already. Besides the IBMs and their descendants, there is a very nice NMB Hi-Tek with clicky black switches that is native PS/2, as I remember, and there are multiple Cherry 122 variants.

I like tp4's and fohat's ideas expressed here.

Designing a a keyboard from scratch and getting it to work is quite an undertaking.
You (or a close accomplis or 2) will need a wide set of skills in order to pull this off.
Quite possible it will take more than 1 attempt.

Skills needed, offhand, includes:
  PCB design
  Keyboard theory (n-key rollover, polling,...)
  Programming, perhaps in C for any "unusual" features you may have
  Soldering (fairly easily learned, just seems scary to some)
  Case design and construction

Lots of stuff to learn... Most/All of it, I believe doable. (For me I'd worry about the PCB design the most, but then I'm inherently a software guy.) I think all these aspects are cool and worth learning as a hobby, though I prefer to tackle then one at a time. That way I have something to show or my work and learning curve as I progress.

I'm really starting to like fohat's solution... If I may expand...
Get yourself a small keyboard, maybe 40 keys, programable. Plug it into a free USB port. Place it above your Function keys. Program it. (more keys than you'll ever need!) Success!

Maybe take a look at this (Plank, 47 keys): https://olkb.com
