Fractal Design XL HDD Question

[BillHicksRIP]

Built this case last night and it was practically a pleasure to do so. One dumb question though, how do you screw the HDD's in? There's 2 sets of HDD enclosures with removable trays that you place the drives in. The case comes with 40 HDD screws, but I can't work out where to screw them into! There aren't holes big enough in the trays to put the supplied screws through. Unless I'm being thick, which is a distinct possibility. Anyone got any ideas?

Aha. Underneath the drives and trays there are screws to fix from the bottom up. Can't see a dedicated thread for this case but if anyone's thinking of getting one, I'd recommend picking up some 3-pin, 4-pin and ATX 12v extension cables at the same time. Astounding case though.
