I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor.

Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!
