Is a Ghost Hand a cube4you core with F-I cubies? Because I traded for a GH at a meetup recently and I took it apart and it's just that. Well, F-I cubies and a red core, that looks like a cube4you core.
There are a few types of Ghost Hands.
The GH2 is clearly not made with Type F pieces, as it is the cube with a "washboard" appearance on the edges, and centers, with ridges on the sides of the center pieces, partially truncated edges and very rounded corner legs.
The original Ghost Hand (probably the one you are referring to) has similarly shaped pieces, and the cube in general seems to be closely related. I'm almost positive that while GH is a Type F *clone*, it is a different cube.
The red core that you saw was probably swapped out by the owner. I for one replace a lot of my cores with C4U cores because I like the colour (light cube-dark core, dark cube-light core). They probably replaced the core to adjust the cube better, give the cube a better appearance, strengthen the cube, or any combination of those three points.
In short, the Ghost Hand is not just a Type F with C4U core.
