inexpensive GPU mining rig? (not scrypt)

[surfer43]

I want to build a GPU mining rig. I want to get as many MH/s per USD as I can, hopefully 2. But the most important thing is a money efficient computer and PSU for the GPU as I only have a laptop.  I can spend 0.5 BTC max. Any ideas?

And please do not tell me "but 1 GH/S is only $5!"

This is not for scrypt so please don't move to the altcoin subforum. This is for an algo similar (and involving) to SHA-256 and gets about the same hashrates. If you're wondering it is the Skein-SHA256 algorithm.

Ergo it still is not about bitcoin which is the real reason these threads get moved to altcoin.

SHA256 on GPU, wow you really are a modern age punk

I am betting all the ASICs will explode are a myth.

I am not sure if it will explode, but I know they are better for the environment.
