Ok, in today's market whatever version you get (Arcade or Premium) you will most definitely get a falcon so don't worry about that. What you do need to worry about is Lite-on drive, im pretty sure you know something about it...Like the fact its not hackable and you have to spoof your drive which costs you an extra Rs 8k approx.
About the cooling, i've seen some people like incredibulous selling Custom Xbox 360 fans which you can place below your 360 and your console sits on top of it. That cooling mod its pretty good. Another thing you can do is cut open the casing from the top of the GPU and place a fan there. Incredibulous is also doing this mod. You should contact him about cooling 360 modifications. I just X-clamped mine from him, he does a good job.
