You can still dualboot (bootcamp?) the mac's right? If so, I would dual boot that puppy with win7 and go to town. Your hardware is fine and you have addressed the only weakness, the ram. Otherwise start looking at which software you are going to use, the mac stuff or the pc stuff.

The SSD mounting is a non factor. Hell I mounted mine with velcro. They are super light and give off very little heat. So have no worries about that.
