St250 Machine - A Steam Machine inspired case for the BC250

I initially started designing my own 200x200x370mm version of this but then came across 3DCatts SFF Mini ITX Steam Machine Case v2 Airflow and they had nailed the design and was only a few centimetres bigger than the design I was working on so I decided to remix that with Gadgets BC250 to ATX case adapter and have come up with this...

• 4x M3 Self-tapping 10mm for joining the Mid panels together

• 4x M3 Self-tapping 16mm for Mid panel to Power Mount and BC250 & Fan Mount

Parts used in my BC250 build

• For the Main cooling I use Thermalright Aqua Elite 240 ARGB AIO with NexGen3Ds NexGen3D: Version 2 AIO Mount for the BC-250

• For Power I used LightingWill 400W (12v 33Amp) DC Regulated Power Supply This power supply has auto shutdown with less than 2amp draw so I have modified its cooling fan to power on and off with the BC250

• Front fan is be quite! Silent Wings 4 140mm PWM Fan

I have unlocked all 40cu, have 8core enabled and set to 3.5GHz and 2GHz and average gaming temps are around 51*c with this setup!
