Hardware New 3DS XL Super Famicom Edition casing?

[Langin]

So I was browsing on ebay and came across this(Also looked it up on Aliexpress): click

Now I wonder, does someone know a place where I can buy the complete casing for a new 3ds super famicom edition? I'm quite happy with finding these plates but I would love to have the whole system instead.

So, maybe through separate parts I'll get there, so far:

buttons
back housing

What I still need is the inside housing which is a few tints lighter than my Majora's Mask 3DS:

Those buttons are for the small N3DS. They're much smaller than the XL's buttons.

They are..? -_-' Whoops! Thanks you for telling me so.

Edit, are you sure? ;o All the pictures I see on Google they appear to be the same size.
Edit 2, Nevermind! You're right, they differ in the slightest.
