anyone with any guide/tut howto?

as with every model, the more relistic you want it (or the more difficult person you are ) the longer it will take.

the primal structure is done with extrude/rotate/scale combinations, i'll try to give a possible solution, but from there you will have to tweak and tweak and tweak and...

i'll try to make a screenshot and a render to show you the mess i made (pun intended).

you could start with a cube, make it editable and run the optimize command to make sure nothing is seperated.

Then you take 4 (of the 7) parts in front and extrude them several times untill you have the length you need (rotating as desired)

Then you do the same with the other side (as a whole off course), also rotating as desired. Then after that its tedious tweaking time: more rotating, scaling etc... until you have the shape you want.
Good reference images viewed from all sides (front, up, side and perspective) are a plus in such cases, even with seemingly simple objects.

I didt tweak a lot (20 mins i think) and got this:
