I won't have time till later to do a price out for you but:

- Why i7? Unless you do a lot of hardcore audio/video/media work, an i5 is more than enough. I run Premiere and PS (Audition too) through an i5 and it's more than sufficient. The big thing with video work is having an SSD and a HDD. In a budget build the extra $100 could be used on other things (like an SSD).

- A GTX 280 is a pretty damn old card. A modern $200 card would crush it.

- Your PSU will be fine.

- z87 chipset is fine, again unless you are a hardcore designer there's no need to go x79

- There are a lot of low price (~100$) cases that offer quiet solutions. Running a stock CPU cooler wont help though.
