I have started this thread as my new 900D case has just arrived (about 5PM today) so tomorrow morning I will start my new build. The aim of the build is to make a home for my 4 x R9 290Xs along with a RIVE BE, an i7 3970X or 4930k (see which runs best), 2 x 1200i Corsair PSUs, a set of C9 2400mhz Corsair Dominator Platinums and a whole pile of waterblocks. Step 1, Get the cards running on air to make sure there is no problems. Step 2, Get the cards on water. Step 3, Tidy the build up. I start tomorrow morning. Thread Navigation Links.
