Component Deep Dive
Why we selected each of these 8 parts for this build and how they fit into the compatibility ecosystem.
Intel Core Ultra 7 265K
Recommended
The Intel Core Ultra 7 265K serves as the processing anchor for this high-end streaming setup, delivering excellent multithreaded performance without the extreme thermal output of the i9 tier. Utilizing the LGA 1851 socket, this chip features a redesigned architecture that excels at handling simultaneous gaming and AV1 encoding tasks. For 1080p streaming, its high clock speeds ensure maximum frame rates while feeding the RTX 5070 without bottlenecking. The reduced power draw compared to previous generations is a massive benefit inside the cramped thermal environment of the Lian Li A4-H2O.
- Excellent AV1 encoding performance for high-quality streaming.
- Lower power consumption and heat output than previous-gen Raptor Lake.
- Strong single-core performance ensures high 1080p gaming frame rates.
- Requires a new LGA 1851 motherboard, limiting drop-in upgrade options.
- Lacks hyper-threading, which slightly impacts raw synthetic multi-core benchmarks.

NVIDIA GeForce RTX 5070
Recommended
The NVIDIA GeForce RTX 5070 is the ideal GPU for a premium 1080p streaming build, offering next-generation architecture efficiency and 12GB of high-speed VRAM. Its dual eighth-generation NVENC encoders allow you to stream at maximum quality using AV1 without impacting your in-game frame rates. The card's moderate 220W power target fits comfortably within the thermal limits of a mini-ITX enclosure. Paired with the Core Ultra 7 265K, it easily drives high-refresh-rate monitors at 1080p with ray tracing enabled.
- Dual NVENC encoders provide flawless AV1 streaming performance.
- Exceptional ray tracing performance and DLSS 4 support.
- Highly efficient power-to-performance ratio ideal for ITX builds.
- 12GB VRAM may limit ultra-texture settings in future 1440p titles.
- Premium pricing compared to previous-generation 70-class graphics cards.

ASUS ROG Strix Z890-I Gaming WiFi
Recommended
Building a mini-ITX system around the LGA 1851 socket requires a motherboard that does not compromise on power delivery or connectivity. The ASUS ROG Strix Z890-I Gaming WiFi features a robust 10+1+2 power stage design that easily handles the boost behavior of the Core Ultra 7 265K. Its compact layout includes a specialized daughterboard for extra M.2 storage, which is crucial given the physical limitations of the Lian Li A4-H2O case. Additionally, Thunderbolt 4 ports provide high-speed capture card integration for professional streaming setups.
- Robust VRM design easily handles Core Ultra 7 power demands.
- Dual Thunderbolt 4 ports support high-end external streaming gear.
- Clever space-saving daughterboard expands storage and audio connectivity.
- Extremely high price premium for the mini-ITX form factor.
- Tight clearance around the CPU socket limits air cooler compatibility.

Cooler Master MasterLiquid 240 Atmos
Recommended
Cooling the Core Ultra 7 265K inside an 11-liter case requires an efficient liquid cooler that fits strict height limits. The Cooler Master MasterLiquid 240 Atmos is one of the few high-performance 240mm AIOs that physically fits the 55mm pump block clearance of the Lian Li A4-H2O. Its dual-chamber pump design operates quietly, ensuring pump noise does not bleed into your streaming microphone. The radiator and SickleFlow Edge fans are optimized for high static pressure, pushing heat out of the top exhaust of the case efficiently.
- Low-profile pump block fits perfectly in strict ITX cases.
- Quiet pump operation prevents background noise on stream audio.
- Excellent thermal dissipation for high-wattage Intel CPUs.
- Installation can be tedious in cramped small form factor layouts.
- Custom software is required for advanced ARGB lighting control.
