This choice prioritizes cost-effectiveness without sacrificing thermal performance for typical loads. For those seeking even better cooling or planning to overclock, the Phanteks XT M3 case can accommodate beefier air coolers, such as the Corsair A115, and even supports up to a 360mm AIO liquid cooler. This flexibility allows for future upgrades as your needs evolve.

RAM: Speed and Capacity for Modern Gaming

This $800 gaming PC equips 32GB of DDR5 memory from Kingbank, clocked at 6000MHz with a CAS latency of 36 (CL36). This memory kit, priced around $70, strikes an impressive balance between performance and affordability. While a CL30 kit might offer slightly tighter timings for an extra $20, the CL36 option still provides excellent speeds for demanding games and multitasking. The video highlights how the motherboard supports these faster memory modules, ensuring you can upgrade if your budget allows for an even snappier system.

Storage (SSD): Fast Loading, Smart Compromise

For lightning-fast game loading and system responsiveness, the build incorporates a 1TB PCIe Gen 4.0 M.2 SSD from Teamgroup (G50 series). This drive delivers read and write speeds exceeding 1,000 megabytes per second, which is more than sufficient for most gaming and content creation workloads. The video notes this is a DRAM-less SSD, a common compromise to hit budget targets, saving about $20 compared to a DRAM-equipped alternative like the G70. While a DRAM controller can offer “insurance” for sustained speeds over time, the practical difference for most users remains negligible, making this a smart choice for an affordable gaming PC.

Case: Airflow and Aesthetics

The Phanteks XT M3 Micro-ATX case, retailing around $70 in the United States, is an exceptional find for this DIY PC build. Its “almost dual-chamber” design optimizes airflow and cable management without the bulk of a full dual-chamber chassis.
