Nuts!!
That's the side I don't know about - the fiddly stuff inside (I work on a 'this part works and this part works - let's repackage it for my purposes' basis, without actually knowing what exactly an IDE controller etc. is (I know what the IDE controller does (as far as allowing a HDD to be installed and read by the machine), but I couldn't recognise one or make/fix one))
I'll have to see what systems I end up with before I know exactly how it's going to work - from what you said (Bloodline), it may end up based on the A600.
As for 'it can't be taken apart' - wanna bet? :-D (if it was put together in pieces, it'll come apart in pieces - unless there's something you know that I don't or you meant the mobo itself)
