If it helps, I've had a 60G since shortly after launch and it gets ungodly hot. I've played it for 20+ hour stretches and haven't had any issues yet. I also know someone who's had his on since Jan 07(Folding@Home when not gaming) and his is doing well. Mine has about the same air clearance as yours does, so you're probably fine.
