Thanks everyone for your thoughts. My own requirement has stretched out for a bit longer, due to SU5 easing the timetable for replacement but having had a Corsair case and rad for over 10 years of problem free running, my ideal is going to probably be a Corsair H115 (280) Capellix AIO inside a Corsair 680X case. I am all ears if anyone else has thoughts though and besides, if it helps others, then even better.
