Putting it All Together
Now all I needed was a case and a PSU. I had decided that I wanted a modular PSU and a case with decent cable handling, room for expansion and plenty of drive bays. I eventually settled on the Fractal Design Define R4 Case. The case turned out to be a bit larger than I had imagined but proved simplicity itself to build the system into. But best of all, nice and quiet. If you are interested, a quick search will bring up plenty of reviews. For example.
As for power I turned to a unit stripped from an old workstation, a 650W Be Quiet Dark Power PRO BN073. Unfortunately this is now an end of life item but it obtained excellent reviews while available.
It Lives !
A small problem came to light after a bit of use. Cooling. I noticed the processor was running on the warm side even when not doing a lot. To be safe, I swapped the factory heatsink / fun unit for a Noctua NH-U12S. The temperature difference was remarkable. My advice ?, chuck the factory unit in the bin.
