I got a price today from Arctic, so I'm going to order the lid, and see how (if) it fits. I thought of trying to roll the bead inward, since my drum is still sealed. I grabbed it with a big pair of pipe pliers and tried to bend it inward- didn't budge. I'll try the BFH and see what happens- that ought to piss off the neighbors! I'm also collecting all of the other bits and pieces for my build- all SS, other than the fire basket.
I'm very intelligent, but I mask it by doing stupid stuff.
