Originally built this in early 2013 in a zalman z11 case, psu failed just after Christmas so decided to make a few upgrades at the same time. Needed a more up to date case to fit in a corsair h105 that keeps my i5 3570k @4.6ghz very cool.
Did try a phanteks enthoo pro m nice case but couldn't live with how flimsily the side panels where, it was also awkward to get them on. Decided I wanted a more sleek looking case so tried a fractal define r5 nice case again but I did not like the door as its not magnetic and wanted a larger window so tried the define s but missed my optical drive. Did buy a external drive but didn't like it when burning cds to much vibration. Also the define s case I had, when the left side panel was off the case rocked on its feet was fine with the panel in place.
Seen the Thermaltake f31 and it looked like a cross of the fractal define r5 and define s I know the case is like a copy but for my needs its better suited for what I want if the define r5 had a larger window that would have been the case for me but as things are am now happy with the thermaltake f31.
