The HDD is most likely OK. CHeck the video card and the CPU on another board (see if you have a friend who can help you with this).
I'm 99% sure the PSU is fried, but like I said, try getting it replaced.
Same for the othercomponents, althought you might have no luck.
I've got no problems recommending that people try to rip off large corporations. The costs will go up anyway, or will stay low anyway since they need to be competitive. Someone somewhere in the world can be 50 Million dollars poorer, I'll take that great sin upon my soul.
Look at gaz prices. Not exactly "competitive" are they? Yet we're all paying through the nose for it. But I digress.
This is a hardware forum, not a moral etiquette class. THe point is to help the OP. Besides we all know that anyone here would try to return fried hardware if they thought they had a decent chance for a refund/replacement, no matter how many times you go to church per week.

Feel free to drop the ethics hammer.
