I'm all for cool console mods, especially when it's something old-school like an NES. However, sometimes I see one that makes me stop and wonder why on earth someone would make such a creation. Take, for example, this light gun which has an entire NES stuffed into it.
There's no benefit to having your console and controller shaped into a gun, so it seems rather pointless. Now if said gun actually worked with Duck Hunt, and that was the only game you used it with, then I guess you'd be onto something. Well that's exactly the point behind this mod.
I'll definitely give it points for originality, however, if the person ever wanted to play some Mario Bros. or something, they're likely going to find it rather uncomfortable to play.
