I'm not trying to be stickler, or to come point out shortcomings, but I just wanted to add a mention. Friendly criticism.
I was actually in the market for an H100i yesterday, and the inherent flaws of buying or trading off of any forum (no matter how reputable) is always going to be a detractor. So offering an item for one dollar less than Amazon, shipped, probably wont pull any buyers. I've got Amazon prime, so 2 day shipping, from Amazon, where I know I'm guaranteed a return if the item is lost or broken, made it a clear choice for me.
If you want to draw in buyers, you'll have to make some price reductions. You're not a store, you can't guarantee anything, so people are willing to pay 5 or 10 dollars more to have that assurance. No one here can hold you accountable if something gets lost or shows up broken.
