IMHO, this is a terrible idea and you won't get backed.
Also, your little prizes suck
Hand signed certificate? Those are just the computer generated ones right? 😛
No one will donated 250 dollars just to have their name on a GPU or whatever
No one will donated OVER 250 when they literally acquire nothing.
I won't donate to this because I'm not getting any returns. All I would get are some lousy emails, certificates, and my name etched on something I'll never have.
Parts list:
200-300 dollars cases? dumb, could get a much cheaper case and put more money towards GPUs or CPUs
An assortment of mobos (2011, 1155, and AM3+?), just choose a platform and stay with it
GPUs, holy crap. 1 690 and 4 580s? and plus 8 680s and 5 7970s?
CPUs, you get an extreme edition and cheap out for a 3930k on the other?
Assortment of ram and assortment of other stuff
Seems like you're just trying to fund a hobby.
I wouldn't donate a dime.
