Mayweather vs McGregor: Prepare the cash prize Introduction

On the 26th of August, 2017, Floyd Mayweather, Jr. will face up to Conor McGregor in a boxing match.

Both participants will receive the phenomenal amount of 100 million dollars!

Unfortunately, we do not have the money yet, but we can already prepare the big briefcase that will contain all the banknotes.

The briefcase is composed of _,|,= and $.

It has a size of 41 characters in width (ignoring the newlines) and 6 in height (+2 for the handle).

Challenge

Given no input, write a full program to output a 2D briefcase (see above).

Score

This is code-golf, so the shortest solution (in bytes) wins.

How?

Step 1. Build a list of the rows of the right half of an empty briefcase, ignoring trailing spaces:

⁽©Ḍṃ“_= ”x"“€Þ‘x2,6¤;"⁾_|x1,7¤
    “_= ”                      - literal list of characters = "_= "
⁽©Ḍ                            - base 250 literal = 2674
   ṃ                           - base decompress (2674 in base: 1='_', 2='=', 0=' ')
                               -   ...yields the list of characters: "_ =    _"
                   ¤           - nilad followed by link(s) as a nilad:
           “€Þ‘                -   literal list of code page indexes = [12,20]
                2,6            -   literal list of numbers = [2,6]
               x               -   repeat -&gt; [12,12,20,20,20,20,20,20]
         x                     - repeat -&gt; ["_"*12, " "*12, "="*20, " "*20, ..., "_"*20]
                             ¤ - nilad followed by link(s) as a nilad:
                      ⁾_|      -   literal list of characters = "_|"
                          1,7  -   literal list of numbers = [1,7]
                         x     -   repeat -&gt; list of characters "_|||||||"
                     "         - zip with the dyad:
                    ;          -   concatenate -&gt; ["_"+"_"*12, "|"+" "*12, ...]


Step 2: transform that into a whole empty briefcase:

z⁶ZUŒBY
 ⁶      - literal space character
z       - transpose with filler (adds the "leading" spaces, to the 1st 2 rows)
  Z     - transpose (back from columns to rows again)
   U    - upend (reverse each row to make it a left-hand side of an empty briefcase)
    ŒB  - bounce (add a reflection of each row with one central character)
      Y - join with new lines


Step 3: Show me the money!
