A chassis isn't just a metal box — it's a commitment to a growth trajectory. Choose the wrong one and you're rebuilding from scratch. Choose the right one and your infrastructure scales with you.\u003c\/p\u003e\n\n\u003cp\u003eDVUN's Chassis \u0026amp; Expansion collection is built around the principle of \u003cstrong\u003emodular forward compatibility\u003c\/strong\u003e. Every chassis we stock is selected not just for its current configuration, but for its expansion headroom: additional GPU slots, PCIe expansion bays, hot-swap drive cages, and power supply upgrade paths. Whether you're building a new compute node from scratch or expanding an existing server's capacity, this is where the physical architecture of your AI stack takes shape.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eWhat Makes a Chassis Worth Buying?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpansion Slot Density:\u003c\/strong\u003e The number and type of PCIe slots determines how many accelerators, NICs, and NVMe cards your system can ultimately support.
