How does this case work?

[charlener]

I bought a case (generic 300W midtower) and looking through the bits, I can't quite figure out how to install the mobo. The mobo tray has these large holes that you stick these metal clips(?) in...I can see how it'd support the board but not how you could physically keep the board in. Anyone have a clue?

The best thing to do would be to read the manual. If it didnt come with one, go to the manufactuers site and it will probably be there.

Here's a guide and more than likely there is a screw that holds that tray in place. Mine only has one screw holding it if the side of the case is off w/side on it is then 3. The other thing that will hold it in are your pci/agp ect,it's not alot holding it in but I try not to take mine horseback riding, skydiving ect.
