Tradeoffs
To fit the RTX 5070 and Core Ultra 5 245K within a strict $1500 target, we opted for a fast 1TB SSD rather than a larger 2TB drive out of the box, requiring active storage management. Additionally, choosing a Micro-ATX form factor limits extra PCIe expansion slots compared to full ATX, though it significantly reduces the overall footprint while preserving optimal airflow.
