The plan here was to take my old ATX i5 2500k system and transplant it into a Raijintek Styx Micro ATX case, with the only changed parts being a refurb motherboard (Asus P8P67M-Pro) and Noctua NH-D15S.
That failed miserably when after 1 evening of use the motherboard started to die. Within two days I gave up and decided to reassemble my old PC, but excluding GPU, HDD, SSD and with it's original CPU cooler and PSU. Sell than to fund a Haswell upgrade as my new Oculus Ready PC.
So the new build went smoothly, I have some more Noctua case fans to add before I start to push the overclocking options. The mission with this build is to create an Oculus Ready, Silent overclocked PC on air and in a subtle MicroATX case
The learnings from this build are:
1) The Noctua Nh-D15S is still massive, so covers one of the motherboard screw points. Therefore one fixing cannot be used.
2) You'll need some Sata power adapters that are nice and flat to mount HDD & SSD to the flat plates in the Raijintek case. My HDD isn't mounted yet as the first trial run I had with it sounded very noisy compared to the rest of this near silent system.
3) Airflow is key, which is why I'm adding more casefans. I have the CPU heatsink fitted the wrong way round so that it clear the fan mounting point on the case floor. This means I've got the assymetrical heatsink completely covering the first PCIe slot, but with my PSU that's not a problem as my GTX980 is too long to fit in there. A future upgrade will be AIO watercooler, shorter PSU (Fractal Integra 750) and a 2nd GTX980 for SLI.
