Recommended for gaming, GPU-accelerated creative work, 3D or graphics-heavy tasks, larger multitasking workloads, and local storage expansion. Consider Custom_Mod SX1 ITX if you want a larger performance-focused mini PC built around its listed AMD r5 5600 processor and AMD 7800XT discrete GPU plus integrated graphics. It is performance-oriented rather than ultra-compact, so it is better suited to users who can accept a larger mini PC chassis.

Custom_Mod SX1 ITX features AMD r5 5600 with AMD 7800XT discrete GPU plus integrated graphics, offering 1× 2.5G Ethernet, HDMI 2.1, and expanded internal storage. CPU details include Zen 3 CPU generation, 6 performance cores, and 12 threads. Memory support includes up to 64GB RAM across 2 slots at 4400 MT/s. Storage support includes up to 4 storage drives including 2 NVMe SSD slots, 2× PCIe Gen4 x4 NVMe, and 2× 2.5-inch SATA bays. Display support includes support for up to 7 displays. Port connectivity includes 1× HDMI 2.1 and 1× PCIe x16 expansion slot. Networking includes 1× 2.5G Ethernet. Physical design includes a 305 × 185 × 120 mm chassis (6.77L). Cooling information lists 120 mm main fan.

Based on its overall score of 368.3, Custom_Mod SX1 ITX is positioned as a high-end ranked mini PC entry in this dataset; compare it against alternatives by CPU class, GPU type, memory ceiling, storage expansion, LAN, and port selection.

Verdict

Best for

compact gaming, GPU-accelerated creative work, larger multitasking setups, local storage expansion.

Avoid if

you want a silent, ultra-low-power office box; you need a high-speed external-GPU or advanced docking path; you need multiple high-speed LAN ports for router or NAS duty.

Alternatives
  • Bosgame M4 8745HS — better value at comparable performance
  • Lenovo P3 Ultra 13900 A5500 — higher performance ceiling
  • GMKtec/Morefine Nucbox K11 4090M — adds OCuLink for external GPU expansion

Review

The Custom_Mod SX1 ITX is a small-form-factor mini PC built around AMD r5 5600 and AMD 7800XT discrete graphics. With a listed price around $1,310, it is aimed at buyers looking for compact gaming, GPU-accelerated creative work, larger multitasking setups, local storage expansion. The core spec sheet is solid for its class: up to 64GB RAM across 2 slots at 4400 MT/s, up to 4 drives, including 2 NVMe slots (2 PCIe 4.0 x4 NVMe, 2.5-inch SATA), 1×2.5GbE, and 1 HDMI 2.1. Its 368.3 overall score puts it in the upper-middle part of this mini PC database, making it a credible shortlist candidate rather than just a budget filler. The main reason to pause is fit: avoid it if you want a silent, ultra-low-power office box; you need a high-speed external-GPU or advanced docking path; you need multiple high-speed LAN ports for router or NAS duty. Overall, the Custom_Mod SX1 ITX makes the most sense when its CPU/GPU balance, port selection, and expansion profile match your workload; otherwise, compare it against similarly priced mini PCs with better networking, quieter cooling, or stronger upgrade paths.
