Is a SSD really worth the money though?
Depends on what you want to use it for. On business apps like Adobe Acrobat I notice huge speed increases on tasks that used to take me 15 minutes now takes a matter of seconds. On games I notice drastically different loading times.
That build looks good - but I'd actually spend a bit less on the case and put that elsewhere, maybe in storage and upgrade to a 1 - 2TB HD. The 600T is a great case but it is quite a bit expensive. What's the max budget you're looking to spend?
