Don't see the reason to have your apps on a separate SSD. I have a 128 that the o/s and all my apps on it (indesign, cs5, illustrator, and ect) and runs with now issue then a second normal hdd that I keep games and content on.
here is a quick build for ya.

That will put you at $952 plus shipping. since the card reader has 6 usb ports you could get a cheaper motherboard to drop the price a bit. I would add a second drive for storeage.

Would add $80 to your price. You would still need a O/S, that is a quick build with decent gear. I built it more as a gaming PC but it should tackle any thing you would throw at it image wise. The Video card may be a bit overkill as well.
