Alienware alpha custom modify? cooling fans and case

I used my alpha for a few months. I upgraded the cpu to i7, hdd to ssd, ram  and  I really like it, although the gpu is average and cannot upgraded. Now, I am wondering that can we replace some parts like cooling fans, case, etc. I really hope someone or DELL can make more parts (like stronger cooling fans, transparent case) for us to customize our alpha. Did anyone think about that or seem anything about that. lol =D
