Just a few thoughts...
I'm not a huge fan of having miners setup in a room with carpet
My miners are in a room with carpet. Why do you not like that setup?
HiSoC8Y:
You might want to wrap the paper clip in electrical tape, or put it off to the side so nobody touches it.
No pets should be able to get into that room.
The power supply in the middle is fine.
And yea, you might want to tape together the wires and put the against the wall. You don't want anyone tripping over them, and breaking all the miners.
