A desktop upgrade kit swaps three parts at once: the processor, the motherboard it sits in, and the memory that board accepts. Those three are locked to each other by socket and DDR generation, so changing one normally forces the other two. Buying them together removes the compatibility guesswork for anyone reviving an ageing office, study or first-build machine without disturbing the case, drives or graphics card.

Choose the platform before the price. Entry Intel bundles at this level sit on LGA1700, the socket that ended with Intel's 14th generation, and each board takes either DDR4 or DDR5 but never both. That one decision fixes what memory you can add later, which carries more weight in 2026 than it used to because DRAM pricing has climbed steeply while manufacturers divert capacity toward AI memory. Orders leave the Centurion warehouse for 1 to 3 business days to Johannesburg, Cape Town, Durban and Pretoria, and 3 to 5 days to regional addresses.
