Thank you both for your time responding to my post. I know you have lots of insight as demonstrated on other threads so it is of value to me. I think I was possibly not clear in my first post - this is actually my rack - I was given the 'rack' itself and a number of other modules and already had the System 1m (which I really love) hence it lives in there, but as you can see I am out of room. Not an issue as such as I am slowly learning what I have and am not in a rush to expand. As you noticed I entirely agreed with the point that the 1m need not be in there, but your points regards the Autobot and M303 are well made. They were bought several years ago on something of a whim and sat awaiting the rack. I do love them but if they take up room that is not required then it is a fair point well made.
On the other hand as I already have this rack and the System 1m removal frees up some space, perhaps my asking what could be of value to you in the space it leaves would be a fair question?
Thanks again - a pleasure getting to know you all.
Paul
