ok boxgods trying for rma called frozen cpu , they said for faster service to call Brian at primochill, so hopefully he can help me out ... luckily i didn't epoxy.... just didn't want my main pc out another 2 weeks it good to hear they're changing out the screws for nylon ones , but I had to use 2 way tape cause of the position of the screws and yea one rail definitely lets it rotate a bit but once i put in the cdroms she locks in , the back piece is the 1/4 but it was pretty sturdy and held my swiftech pump great .... all and all this reservoir was a bit of a problem , but after i heard it running I was amazed at how well it worked , hopefully if I can get a another one Ill have my confidence back in it
