What to do with $840 Worth of Broken Computer Parts?

Ok, so my friend's uncle thought it would be cool to buy about $1500 worth of parts for his nephew last Christmas. I got to help him put the water cooling together ! At first, it was a Q9650 Quad Core CPU, 4GB DDR3 1600 ram, 800ish watt psu, Rampage Extreme motherboard, and an ATI 4870 video card with 512MB of DDR5. And a giant full tower case with water cooling for the CPU, northbridge, and video card. It was a very impressive setup until the 4870 started displaying artifacts on the screen. So his uncle says, "No problem, I'll just send you one of my 4870X2's and a new power supply for it!" Which is exactly what he did. Unfortunately, this new SilverStone 1200 watt psu will not turn on for the life of me. It will only click, giving power for about 1/2 a second, then turn off. The 4870x2 displays gray lines across the screen, so we figured that my friend's uncle left coolant in the waterblock, which got out during shipping and damaged both the card and the power supply. So his uncle then sent him his OTHER 4870x2 and ANOTHER power supply, and those two seem to be working fine now.

Well, the two expensive video cards and the ridiculously powerful power supply are now in my possession. Unfortunately, the uncle does not believe in receipts, so I don't have much of a way to get warranty work on these amazing pieces of computer hardware. The waterblocks could bring some money, though.

Does anyone have any idea how I can get these hardwares to work or sell them to someone for a decent amount of money?

Thanx,
Brijar!!!
