The project

Create a small mining rig for burst.
The goal was to be very 'green' because Burst is supposed to be a green coin. Also I wanted it to be 100% silent.

The PC

As this is my first attempt, I went for a cheap barebone fanless pc: Hystou with celeron (2 cores) -> 140$

Advantage:

• cheap
• 0 noise
• screw to fix it easily
• 4x USB 3 ports
• 4x USB 2 ports

Disadvantage:

• slow
• only 2 cores

Hard drives (to start... maybe more to come)

Bought 3 x 5TO external usb drives portable (110$ each):

Why external portable usb drive ?

• no need external power supply (usb powered)
• cheap
• easy to resell or reuse later

Disadvantage:

• veryyyyyy long to plot directly

The frame

Then I build a very simple wood frame... This could be far better but I am not a woodworker expert at all:

I made it so that pc and hard drives have space all around to cool.

Final result

Notice the gap under the pc, to optimize cooling (cooling it done passively through the case)

The result is 100% silent (except hard drive, but you really need to have your ear very close to hear them).

For the moment I plugged 2 x 5 TO + 1 x 1TB hard drive.
At the moment it's already mining 7 TB of burt and some storj easily.
I will publish the mining result in a few weeks, when I have more data to share.

Conclusion

Very happy so far. Still need to plot more drives to see the max capacity it can scan. Also I am already planning some improvement for the next version (more cpu cores, better frame etc.).
