How to build a high-performance Mini ITX gaming PC in 2019? Compact Mini ITX builds require careful component selection prioritizing space efficiency and thermal performance. Key elements include SFX power supplies, low-profile coolers, and GPU clearance optimization. The 2019 market offered revolutionary small-form-factor cases like NZXT H210 and RTX 20-series GPUs that balanced power with reduced footprints.
Why Choose Mini ITX for Gaming PC Builds in 2019?
Mini ITX motherboards (170x170mm) enabled ultra-compact systems without sacrificing modern features like PCIe 3.0 and DDR4 support. The 2019 hardware landscape saw AMD’s Ryzen 3000 series and Intel’s 9th-gen CPUs delivering desktop-grade performance in ITX configurations. Cases like Lian Li TU150 introduced innovative handle designs for LAN party portability while maintaining 320mm GPU compatibility.
What Components Work Best in 2019 Mini ITX Builds?
Critical 2019-specific choices included NVIDIA’s RTX 2070 Super (dual-slot, 267mm length) and AMD’s Radeon RX 5700 XT reference design. SF600 Platinum PSUs became the gold standard for reliable power delivery. Noctua NH-L9i chromax.Black coolers addressed both height restrictions (37mm) and aesthetic demands. Crucial Ballistix Sport LT DDR4-3200 emerged as top RAM for clearance-conscious builds.
How to Manage Thermal Constraints in Compact Cases?
2019’s thermal solutions combined negative pressure airflow designs with liquid cooling innovations. The NZXT Kraken X42 (140mm radiator) proved ideal for cases like Phanteks Evolv ITX. Custom fan curves using BIOS utilities or SpeedFan software became essential. Thermal testing showed 5-8°C reductions using hybrid GPU coolers like EVGA’s iCX3 technology in confined spaces.
Advanced builders experimented with sandwich-style case layouts to separate CPU and GPU thermal zones. The popularity of 92mm AIO coolers like the Cooler Master MasterLiquid ML90L allowed overclocking headroom in sub-10L cases. Third-party modification services offered CNC-milled ventilation patterns, improving airflow by 12-18% based on computational fluid dynamics simulations. Undervolting through MSI Afterburner became standard practice, with RTX cards showing 15% power reduction while maintaining 95% performance.
Which 2019 Cases Maximized Mini ITX Potential?
The Cooler Master MasterCase H100 redefined vertical ITX layouts with 240mm radiator support. Silverstone’s RVZ03-ARGB pushed console-style designs to accommodate 330mm GPUs. Ghost S1 clones flooded the market, offering modular stackable configurations. CaseLab’s Bullet series introduced military-grade aluminum construction for premium portable builds.
How Did 2019 GPU Developments Impact ITX Builds?
NVIDIA’s Super refresh brought 2060/2070/2080 variants with improved power efficiency – crucial for SFX PSUs. AMD’s 50th Anniversary Radeon VII showed 16GB HBM2 could fit ITX form factors. Partner cards like ASUS Dual Evo OC series optimized PCB layouts for SFF compatibility without performance loss.
What Were the Hidden Costs of 2019 ITX Building?
Beyond premium case pricing ($150+), builders faced “ITX tax” on components: SFX PSUs cost 40% more than ATX equivalents. Low-profile DDR4 kits carried 15-20% price premiums. Custom cables became mandatory for clean builds, adding $50-80. Liquid cooling required expensive slim radiators (Hardware Labs Nemesis 240GTS) to maintain airflow.
| Component | ATX Price | ITX Premium |
|---|---|---|
| PSU (600W) | $89 | $129 |
| DDR4-3200 (32GB) | $140 | $165 |
| CPU Cooler | $45 | $75 |
Enthusiasts often spent $200+ on custom loop components specifically engineered for SFF compatibility. The shift to PCIe 4.0 SSDs added another cost layer, with 1TB Gen4 drives commanding 60% premiums over SATA alternatives.
How Did 2019 Motherboards Address ITX Limitations?
Flagship boards like ASUS ROG Strix X570-I Gaming included PCIe 4.0 support and dual M.2 slots with backside heatsinks. VRM designs improved dramatically – Gigabyte’s Z390 I AORUS PRO used 6+2 phase power for stable 5GHz OC. USB 3.2 Gen2 front-panel headers became standard, supporting high-speed cases like Fractal Design Node 202.
“The 2019 ITX revolution wasn’t just about size – it forced engineering breakthroughs. We saw vapor chamber designs shrink to fit 2.2-slot GPUs, DDR4 reaching 4400MHz in tiny DIMMs, and PSUs hitting 80Plus Titanium efficiency in SFX-L format. These innovations laid groundwork for today’s sub-10L powerhouse builds.”

Conclusion
2019 marked a watershed for Mini ITX gaming PCs, blending cutting-edge components with unprecedented density. While requiring meticulous planning and premium investments, these builds demonstrated that desktop-grade performance could thrive in sub-20L environments. The technical solutions pioneered during this era continue influencing compact PC design philosophy today.
FAQs
- Could 2019 ITX builds handle 4K gaming?
- Yes – configurations using RTX 2080 Super GPUs paired with 9700K/3700X CPUs achieved 60+ FPS in 4K across AAA titles when using optimized settings. Thermal constraints required undervolting GPUs by 50-75mV for sustained performance.
- What was the smallest viable 2019 ITX case?
- Velkase Velka 3 (3.7L) supported 175mm GPUs like Zotac 2070 Mini. Required flex PSUs and demanded specialized 37mm CPU coolers. Typical builds ran 5-10°C hotter than larger ITX cases but proved ultra-compact gaming was feasible.
- Did PCIe 4.0 impact 2019 ITX builds?
- AMD’s X570 boards introduced PCIe 4.0, allowing 16Gbps M.2 speeds. However, most 2019 GPUs couldn’t saturate PCIe 3.0 x16. The tech previewed future storage advantages rather than immediate gaming benefits.
