Have you actually ever received anything from these guys?  Are they reputable?

I've met them personally, we have some mutual friends, and I was actually just featured on their blog.  I wish them the best of luck, even though they reached the Kickstarter goal, I would still contribute because the more money they get the more difficult things they are going to try to accomplish, traveling for example.

Best of luck to Austin and Beccy!

I used to be an avid Folding@Home guy.  I work for a company in the Supercomputing field and we had lots of servers sitting idle most of the time.  I got us pretty high in the Folding@Home arena and then realized I could be making money doing the same type of work.  It was a no brainer to switch from Folding@Home to Bitcoin.

I've since made several thousands of dollars and am still going strong.

I like your idea.  I actually am in the process of finalizing a kit for stackable bitcoin mining rigs.  I'll let you know when I post it.  I think it would fit what you're looking for perfectly.

Good Luck!

I took the approach of buying older hardware off ebay for very cheap.  I have built 3 dedicated rigs, each one with 4 modern Graphics Cards. 

$40 for the motherboard
$5 for the CPU
$6 for the CPU heatsink
$2.50 each for PCI Riser

I had extra RAM and HDD.

Let me know if you are interested in the specific hardware I'm using.
