For cluster rack I chose TUFFIOM 9U Network Cabinet Enclosure and added connectors to it to avoid pull wires from outside through holes, i.e. isolated it from outside.
Holes for mounting closed by 3M Fire Barrier.
This rack come with 2 x 110V fans which I replaced by 2 x 120mm 12V fans. Also was added 2 x 120mm 12V to each rack side.
In the inside I put 2 x automatic fire suppressor StoveTop FireStop Rangehood. This is "class K" fire suppression which supposed to use on the kitchen but from reviews I found that is also works for electronics as it dry-chemical fire extinguisher. Once I will find good alterntive it will be changed to "class C".
On front side plate was placed UPS, rack-cooling and reserved place for other electronics like rack-alarm, security alarm, etc.
On back side plate was placed Power supply modules with 5 x 50mm 12V fans and power supplies with monitoring module and other sensors.
