Here is what I have so far. You'll notice i'm not destroying any classic hardware.
A new c64c case from original mold. --> http://www.ebay.com/itm/New-Vintage-Style-64C-Computer-Housing-Case-White-/332045168279
Raspberry Pi 3
NOS Commodore 16 keyboard from Radio Shack : #277-1027
Keyrah V2 by Individual Computer (in the mail from Vesalia ) --> http://wiki.icomp.de/wiki/Keyrah_V2
SidPi (which I'l need to build) --> https://oshpark.com/shared_projects/vRw7mWuD
unfortunately my SID chip is an 8580
so far... I've cut a square of lexan (plexiglass) to match the footprint of the original c64 MB, but I think I'll have to trim a little away to fit the Keyrah when it arrives.
I'm also waiting for HDMI and USB extensions to arrive (from China) before I really have an idea to the layout.
What do you think? Any ideas?

Im doing the same . I havent sourced a case yet , shipping from that place in Texas to the UK was ludicrous. But i have some key caps on order. Nice that you have managed to a NOS keyboard though!
Im thinking of doing a Cherry MX mod to mine as the keyboard on my is a bit patchy at the best of times. Instead of a RPi im using a C64 Reloaded board - which works quite nicely.

This is very cool :)
I was not aware that the keyboards are so readily available.
-
So what happens when the SID is connected to the Pi?
-
Pretty cool idea.
I like the idea of enclosing the Pi in a C64 case and attaching a SID to it.
I might have to replicate this, even if I don't use it for Commodore emulation.
It would make a nice system.

It's a shame the shipping excessive. The case is really nice at a very reasonable price. It even included some custom stickers.
I like C= 16 KB has distinct cursor keys unlike the C= 64 KB.
I forgot about the manual shift-lock. I like that too...

I'll probably run RetroPie image and use it more for the emulation of other things as well as Kodi player.

hopefully you'll have a working "/dev/sid" and this result:

This is probably the biggest challenge for the entire project because the SidPI is based around the 6581 SID and I have the newer 8580 chip...
The main differences of the two SID chip types:
SID 6581 needs 12 V DC voltage and two 470 pF filter capacitors
SID 8580 needs 9 V DC voltage and two 2,2 nF filter capacitors
(http://personal.inet.fi/musiikki/jtpartanen/commodorestuff/6581to8580/index.html)
I'll probably have to have ask someone that knows more about SID chips help me out...
form example this confuses me, the schematic here -->https://raw.githubusercontent.com/papawattu/SidPi/master/schematic/sidpi.png shows the filters already as 2,2 nF which I would think would be correct for the 8580 but the documentation suggests he is using a 6581.

It might be worth contacting Colin Piggott. He makes a SID interface for the Sam Coupé and can tailor it for either a 6581 or an 8580 so he'll definitely know which value caps you need for which version.

Thanks for suggesting him as a resource for the SID, never heard of the (very interesting) Sam Coupé computer before now :)
I contacted the author of the SidPi with a few questions. Hopefully he shoots me a response.
I mean to do this thing up right, I should do DUAL SIDs in stereo.... more of a c65 clone...

The Keyrah V2 came in today...
Using it now to test with with my "Mac" and it's working but a lot of keys are screwed up as what is printed on the key vs outcome. But I guess it's more designed for touch typist...
Its working properly according to http://wiki.icomp.de/wiki/Keyrah_V2
The keyboard has a nice feel though :)
I see the Keyrah wires the joysticks in as keyboard. Just like the old days when someone starts messing with your joystick on the C= 64 and it destroys what you are typing! 2486248624862486248624862486248624862482824842842842842824824626248624865555555555555....forgot about that!

I used to work at Radio Shack back in the late 80's / early 90's. I'm still kicking myself for not picking up one of those keyboards. We had a couple in stock that never sold.
I see them show up on ebay every now and then.

Here is a little update on this project.
I was having regret over not buying the transparent case, so I decided to get one of those as well. I everything is mounted to my plexiglass "motherboard", so its easy for me to switch the cases out anyway :)
I have not started messing with the SID chip yet...

Looks great.

very nice and impressive!
