If you're into retro gaming, you've probably heard of the Miyoo Mini—a compact, nostalgia-inducing handheld. The plastic version is affordable, but recently, third-party manufacturers(MechDIY) have introduced full-metal custom editions, often priced at $300 or more. At first glance, that might seem outrageous.
But as someone familiar with machining and custom electronics manufacturing, I can tell you—this pricing is actually fair. Let’s break down why a metal Miyoo Mini costs so much.
1. Material Costs: It’s Not Just "a Piece of Metal"
Plastic shells are cheap to mold, but metal is a different story.
-
6061 Aluminum: Chosen for strength, weight, and machinability—10x more expensive than plastic.
-
Material Waste: CNC milling removes a lot of material, with <50% efficiency in small batches.
-
Pre-Treatment: Metal sheets must undergo stress relief to prevent warping.
→ Just materials + basic machining can exceed $80 per unit.
2. CNC Machining: Where Small Batches Get Expensive
Metal shells aren’t cast—they’re CNC-milled from solid blocks, meaning:
-
Programming & Setup: Each shell requires custom toolpaths; low volume = high per-unit cost.
-
Multi-Step Process: Milling the body, button holes, screw posts, and vents—each step needs recalibration.
-
Scrap Rate: A 0.1mm error can ruin a shell; ~20% may be discarded.
→ CNC alone can cost $100–150 per shell.
3. Surface Finish: Anodizing for Durability & Style
Plastic can be painted, but metal needs anodizing to resist scratches and wear.
-
Color Dyeing: Custom hues (e.g., space gray, olive green) require trial and error.
-
Sealing: Prevents corrosion and staining.
-
Low-Volume Penalty: Factories charge per batch—small orders = higher per-unit costs.
→ Anodizing + logo printing: $25–40 per unit.
4. Internal Mods: Metal Isn’t Just a Shell Swap
A metal case introduces new engineering challenges:
-
Electrical Shielding: Metal can interfere with circuits, requiring insulation.
-
Button Feel: Plastic buttons may stick; custom tuning is needed.
-
Thermal Management: Metal conducts heat, potentially affecting battery life.
-
Speaker Acoustics: Resonance changes may dull sound, requiring recalibration.
→ Modifications + labor: $50–80 per unit.
5. Quality Control: Hand-Testing Every Unit
Mass-produced plastic shells get automated checks, but custom metal units need manual inspection:
-
Button Durability (50,000 presses)
-
Drop Tests (metal transfers impact differently than plastic)
-
Thermal Stress Tests (preventing overheating)
→ QC adds $20–30 per unit.
6. Why Can’t It Be Cheaper? The Small-Batch Dilemma
If this were a 10,000-unit order, costs could drop below $50 per shell. But the market for a metal Miyoo Mini is tiny—maybe a few hundred buyers worldwide—so:
-
No Economy of Scale: No bulk discounts on CNC or anodizing.
-
Labor-Intensive: Almost every unit needs hands-on tweaking.
-
R&D Amortization: Design and prototyping costs are split among few customers.
Verdict: Is $300 Fair? Yes—But Not for Everyone
-
For premium feel: The metal version’s durability and heft justify the price.
-
For casual gaming: The plastic Miyoo Mini is the better value.
-
For makers/enthusiasts: This isn’t a cash grab—it’s a passion project with slim margins.
So, the $300 metal Miyoo Mini isn’t a "scam"—it’s the reality of bespoke hardware. Would you buy one? Let’s discuss in the comments!

You’re explaining why it costs so much, not why it is worth buying beyond ego-stroking. Very nice case surrounding relatively inexpensive electronics that are just as likely to fail as in plastic-cased version. For someone into gaming – not electronic jewelry – they will likely get more satisfaction from a more capable device where the electronics merit the $300 price tag.
