You should consider using an escrow service or going first because of your forum 'status', whatever that's worth. I know your account is a year old, but I still even do deals with other other hero members with escrow service because you never know.
Second, I would be more than happy to buy that 1200w PSU from you but you are asking too much. They are $220 new on amazon and if I buy a gift code to cover that purchase from a fellow member it will only cost me $198 for a new one with free shipping.
PM me an offer then. I have no problems using a mutually trusted forum member as escrow. I've also sold a raid card to mclovin. But whether or not he will vouch for me is another thing.
