Ha I have them same numarks, they where my first ever set of turntables. Still in my attic somewhere.
im not sure what exactly you mean, so ill just go down the list
the controller in the middle is the numark total control. i got it for $200 but i heard it goes for 150 now a days
the things on the sides are novation dicers. i won them in a random drawing, but you can buy them from the DJTT store [link below] for $100
[at the time of this post they are sold out, but you can find them elsewhere too]

my total control came with traktor LE, so the traktor pro upgrade cost me $70, and to upgrade now to traktor pro 2 it would cost me $80
i dont know how much the regular price is.
the 5.1 speakers my dad got, so i dont know.
troll face cost 1 sheet of paper and some ink
troll face on your subwoofer = priceless
laptop [dell latitude d531] i dont know. it was a gift.
cooling fan under laptop - not mine. i think its like $50 though.
a 2x4 and keyboard stand and a few screws - cost will very
EDIT: now i get what you meant. it says ‘traktor’ on my total control because thats a sticker 
i emailed NI and got em for free
Maschine does that, I wasnt sure if it was on purpose or if it was a convenient coincidence.
I rescued four of them from the dj booth in an 18 & under club I used to do gigs at. Those kids had beat the sh!t out of 'em. Still work, though. They don’t see the light of day very often.
