As someone already said, go for a Crucial M4 SSD. There have been too many reported problems with the OCZ drives because of the Sandforce controller.
For a motherboard you may want to consider an ASUS P8Z68-V LE. This supports pretty much anything you would need like SATA III and USB 3.0. It also has a Z68 chipset and has great reviews on Newegg.
As for the case, that can be very subjective. If I were you, I would just browse through some of the cases on Newegg. If you are looking for a small case that does not bring a lot of attention, Lian Li makes some nice and simple cases.
