I took a Tosh apart a couple of years ago.
I did get it apart, repair it and get it back together again [though if u looked closely, you could see it was not perfect]
The Tosh was all click into place if I remember correctly.
So it needed a fair pull to get it out
Almost the same pressure as to break the part if you got it wrong
So look at all of the parts all of the time, trying to think logicaly how it was put together
Most of all, lay the parts out in order and the odd note.
If you think its hard getting it apart, wait til you are trying to put it back together so it looks perfect.
