That DMG that John found in a trashcan

HHL Backlight Kit v3 $9.99
    Washed Yellow or White?
    Comes with everything needed: backlight, two wires, polarization film, SMD resistors are preinstalled
HHL Bivert/Hex Module $3.99
    Might not end up installing this, depending on his feedback; a blue screen with more contrast might be less desirable than a screen that retains some of its characteristic green
Housing: Original Gray $11.99
    Will be noticeably less yellow than the housing it's replacing.
    Seems to come with:
        Buttons
        Plastic screen cover (is this preinstalled or separate?)
        Metal shield behind the cart slot
        Battery door
        Link port cover
        Power switch
        Screws
    Does not seem to come with:
        Silicone button pads
        Battery terminals?
Screen cover replacements
    What do we want here? One plastic, one glass? Both plastic? An extra, just in case the one that comes with the housing is preinstalled?
One set of battery terminals $1.99
    If new casing comes with terminals, replace the original casing's terminals; otherwise new casing gets new terminals.
Silicone button pads
    Do we want/need these? The originals work fine, they're just a bit dusty. Extra set for the extra housing?

Important questions:
-Colors!
    -Do we want the Original Gray housing, or something more creative? There are a few transparent flavors.
    -Which backlight color? (I'm not too keen on the RGB backlight, considering that putting in dials to control it would require case modding I'm not comfortable with.)
-Do we want a full set of parts for each housing? There's only one set of the actual electronics that go inside them.
    -Most of these are foisted upon us just from buying a new shell. We'd likely reuse the original buttons/power switch/screws/cart slot shield for the new shell otherwise.
-How much redundancy do we want for the parts we buy, and how much do we want to avoid making a second order if we miss something?
    -There's at least two cases (screen cover, battery terminals) where we can spend a trivial amount extra to avoid a second order.

Initial decisions in case I can't contact John before I buy parts:
-HHL Backlight Kit v3, White $9.99
-HHL Bivert/Hex Module $3.99
-Housing, Original Gray $11.99
-One glass screen protector. Probably will go on the new shell if the plastic one isn't preinstalled. $4.49
-No fresh silicone button pads, the originals are fine.
-One set of battery terminals, as already outlined. $1.99
-Total: $32.45 plus tax and shipping
