Solution

a=abs(x)
b=abs(y)
c=abs(z)
if z==-5 and y==-1 then if x>0 and a<3 then return 3 end if x>-4 and x<0 then return 7-2*x*(x+2)end end
if y==0 and z>-4 and z<-1 then if x>-4 and x<-1 then return 3 end if x>=0 and x<4 then return 7+(x+z)%2 end end
if y==0 and z<6 and(x*x+(z-2)^2<6 or z>1 and a<3)then return 2 end
if a<5 and c<5 and b<2 then return y==-1 and 11 or 0 end
if a<6 and c<6 and b<3 then return a<3 and z>0 and y==1 and 0 or 2 end
if b<3 and(a-5)^2+(c-5)^2<4 then return z>5 and y==0 and a<7 and 9 or 2 end

How it works

This is a detailed 3DO console model with a bunch of distinct features layered on top of each other. The trick is checking the most specific stuff first so it doesn’t get overwritten.

Output ports on the back wall (z=-5, y=-1) come first. The three colored AV jacks use a quadratic formula 7-2*x*(x+2) that maps x=-3,-2,-1 to WHITE, RED, YELLOW. The two BLACK ports sit next to them.

CPU and chips live on the internal floor (y=0). A BLACK processor and a RED/ORANGE checkerboard chip pattern using (x+z)%2.

The CD tray is a disc shape centered at z=2 on the y=0 plane. Instead of min(sqrt(...), ternary) < 2.5, we squared the threshold: x*x+(z-2)^2 < 6 handles the round part, and z>1 and a<3 handles the rectangular slot. Way cheaper!

The hollow interior (GREEN floor at y=-1, empty above) and GREY shell with its front slot come next. Finally, the rounded corners use squared distance (a-5)^2+(c-5)^2 < 4 instead of sqrt(...) < 2, with a YELLOW racing stripe on the front edge.
