Some size concerns for my new gfx card

My new build is getting a 8800gts put in it, and was thinking of putting into current case Antec SLK3000B, got the measurements of the 8800gts (24cm or sumthing long), folded up an a4 piece of paper to match it, sat it on top of my current graphics card to see how far fwd it would go and it nearly touches the drive bay.
Firstly has anyone had a 8800gts running inside this case? If so, just how close was the real card?
Secondly, if the card wont fit decently in the SLK3000 i was looking around at another case, The coolermaster Centurion 5 looks quite good, but I must ask does the 8800gts fit in this case?

Also, does anyone have pics of either card in either case? Id b keen just to have a quick look at them in the case.

BTW, have 3 drives in my drive bay in the Antec, if it was snug down that end, the drives wouldnt be blocking any flow from the cooler would they? All the hot air goes out the back of the computer right?
