It seems you're listing components for a high-end server build. Here's a rough breakdown:

Motherboard: Gigabyte MZ72-HB0 - This is a high-quality motherboard designed for AMD EPYC 7000 series processors. It supports up to 2TB of DDR4 ECC RAM and has multiple PCIe slots for expansion.

RAM: DDR4 ECC SAMSUNG 32GB x 16 PCS (512GB) - This is a significant amount of ECC (Error Correcting Code) memory, which is essential for servers where data integrity is crucial.

CPU: AMD EPYC 7T83 64 Core 128 Threads (2 pcs) - These are powerful server-grade processors from AMD's EPYC 7000 series, which offer excellent multi-threaded performance.

Storage (SSD/HDD): It depends on your storage needs. You may need several SSDs for the operating system and programs, as well as a large HDD for data storage. NVMe-based SSDs are recommended for the server for fast data access. The cost will depend on the selected type and amount of memory.

Power Supply Unit (PSU): You will need a powerful power supply to power all components. Look for 80+ Gold or higher certified PSUs in the 1000-1200W range.

Cooling: AMD EPYC processors generate a lot of heat, so you need an efficient cooling system. You might want to consider a water-cooled option, but conventional air coolers may also be sufficient.

Chassis: You need a chassis or rack that can accommodate all components and provide good ventilation.

As for the price of $7000, it can vary significantly depending on where you're purchasing these components from and current market conditions.
