You should put these custom cases and full rigs on Amazon.com
And on Ebay. You guys just go and type smth like "GPU frame rig" and check Sold
I'm pretty sure that AriesIV10's things will be selling well.
I have a store (also a Power Seller, TopRate Plus) - so I'm paying 10% to Ebay and PP for transactions, dont remember how many percents they charged if you have a regular account
