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 5 245K
Recommended
The Intel Core Ultra 5 245K serves as the computational anchor for this high-end Mini-ITX build, delivering excellent gaming throughput without the extreme thermal demands of its Core i9 siblings. Operating on the LGA 1851 socket, its architectural efficiency keeps power draw low, which is crucial for cooling inside the cramped Lian Li A4-H2O case. While a 1080p target resolution makes this system highly CPU-bound, the 245K's strong single-core boost behavior ensures maximum frame rates when paired with the RTX 5070. It strikes a sensible balance between gaming performance and thermal management, keeping the overall system cost right around our $2000 budget target.
- Great thermal efficiency for SFF builds
- Strong single-core performance for high-framerate 1080p
- Lower power consumption than previous generations
- Requires a new LGA 1851 motherboard
- No hyper-threading limits multi-threaded rendering speed

Compatibility Notes
Socket, memory, power, and case fit should be verified against retailer specifications before purchase.
Upgrade Path
The upgrade path is solid but constrained by the Mini-ITX form factor. The LGA1851 socket will support future Intel desktop processors, allowing a drop-in CPU upgrade later. The ASUS Z890-I motherboard features PCIe 5.0, making it ready for next-gen SSDs and future GPU upgrades. However, RAM expansion is limited to replacing the existing two sticks since there are only two DIMM slots, and any future GPU upgrades must strictly adhere to the A4-H2O's 322mm length and triple-slot clearance limits.
Tradeoffs
To fit this build into a strict $2000 budget while maintaining a premium Mini-ITX aesthetic, we had to make a few compromises. The ASUS ROG Strix Z890-I motherboard eats up a significant portion of the budget ($350), which forced us to opt for the mid-range Core Ultra 5 245K instead of a Core Ultra 7. Additionally, we chose a PCIe Gen4 SSD instead of a pricier Gen5 drive, and stuck to 32GB of DDR5-6400 RAM rather than ultra-low-latency or higher-capacity kits.
