Thanks for that :-). If you change your mind/don't need it, I'll offer to buy it off you. Will pay the £2.50 + 1st/2nd class post.
A bit strange it doesn't open on the other side. How will you change the DVD drive if you had too - is it held in place by some kind of screwless mechanism?
So looks like you'll have to go for an external hard drive caddy.
Btw, do you think you could house & secure a drive below the card reader? I.e. if it has a free compartment below the card reader like in this Dell - see this pic click here. G
