Sorry guys, missed your responses before as they must have come through while I was writing out my reply on my phone (takes me a little longer lol).
Sound advice here! I'm very grateful for your help and advice.
JDFan, although I think I'm going to have to make visual flowchart on your explanation (don't get me wrong, it's nothing to do with how you wrote it, it's just too complex for me to get my head around lol).
So if I go down that route it means I end up with extra hardware too?! I like that idea in itself!

I'm not sure how well my current kit would run with anything more than name thrown at it (i.e. A PlayStation or Xbox emulator for instance) so I wanted to get some specific hardware to cope. Maybe arrow would be a great way to kill two birds with one stone.
Right now I have about 1.8tb of data to upgrade and the cab HDD is just under 1tb. It now has no operating system... Basically I'm in limbo with it all. No worries, I guess I've got to remember to enjoy the journey as well as the destination.
