<p class="text-lg text-gray-300 mb-6 leading-relaxed">
Your three Mac Pro 2013 systems represent a remarkable opportunity. What many dismiss as outdated consumer hardware actually embodies professional-grade capabilities: substantial processing power, generous memory, dedicated GPU acceleration, and carefully engineered thermal architecture.
</p>
<p class="text-lg text-gray-300 mb-6 leading-relaxed">
Combined through clustering and orchestrated by enterprise-class virtualization software, they transform into infrastructure rivaling systems costing tens of thousands of dollars.
</p>
<p class="text-lg text-gray-300 mb-8 leading-relaxed">
The virtualization use case enables hosting dozens of concurrent virtual machines. The distributed cracking use case leverages GPU acceleration to achieve billions of cryptographic operations per second. Beyond capabilities, your cluster provides exceptional educational value and experimental freedom.
