To buy which case is the personal taste and choice. But the rules are: Cooling (how many fans), bottom mounted PSU, size, case material (steel or aluminum), cable management , drive bay or side window.
In the case you post that has the $10 shipping, so it will cost more, if you can one with free shipping. Anybody likes the free.
The PSU I recommend they are $30, and the 430W one is $34, they are 80plus or bronze too. Why not?
