Key Findings: Buying pre-built in Brazil costs R$ 3,500 to R$ 5,500 (i7 + 32GB + 512GB NVMe). Building with local parts: R$ 4,400 to R$ 6,100. Importing barebone and building: R$ 3,200 to R$ 3,450 (best cost, but with risks).
What Is a Mini PC and How Can It Be "Built"
Unlike a conventional desktop, a mini PC has an ultra-compact form factor (usually less than 12 cm per side) and uses laptop components. "Building" a mini PC consists of purchasing a barebone (the chassis with motherboard and processor already integrated) and installing the (SODIMM format) and ( NVMe format) yourself.
This characteristic makes the mini PC market fundamentally different from the traditional desktop market, where piece-by-piece assembly usually generates significant savings. In the mini PC world, the equation is more complex.
Pre-Built Mini PC Prices in Brazil
The table below consolidates prices found in Brazilian stores for mini PCs with recent-generation Intel Core i7 processors, 32GB of and 512GB NVMe or higher. Data was collected between February and March 2026.
| Model | Processor | Config. | Price | Store |
|---|---|---|---|---|
| Dell Optiplex 3070 Micro | i7-9700T (9th gen) | 32GB / 512GB NVMe | R$ 3.500 – 4.500 | Mercado Livre |
| Machenike Mini2 | i7-13620H (13th gen) | 16GB / 512GB NVMe | R$ 3.599 | KaBuM |

Build Cost: Buying in Brazil
The big problem with building a mini PC in Brazil is that barebones with recent i7 processors are rare and expensive in the domestic market. Intel NUC models with 12th gen i7 were unavailable at major stores at the time of research.
| Component | Reference | Price (R$) |
|---|---|---|
| Barebone i7 12a gen | Importado (com impostos) | R$ 2.500 – 3.500 |
| SSD NVMe 512GB Gen3 | Adata Legend 710 / Rise Mode | R$ 500 – 600 |
| RAM DDR4 32GB SODIMM | Kingston / Ktrok 3200MHz | R$ 1.400 – 2.000 |
| Total Estimado | R$ 4.400 – 6.100 |
Build Cost: Importing the Barebone
Direct import of the barebone can significantly reduce costs. Using the GMKtec M3 Ultra (i7-12700H) from the official site at US$ 299, and considering Remessa Conforme taxes:
| Component | US$ | R$ (approx.) |
|---|---|---|
| Barebone i7-12700H | US$ 299 | R$ 1.750 |
| SSD NVMe 512GB | US$ 40 – 50 | R$ 235 – 295 |
| RAM DDR4 32GB SODIMM | US$ 60 – 80 | R$ 350 – 470 |
| Impostos (~37%) | — | R$ 865 – 930 |
| Total Estimado | R$ 3.200 – 3.450 |
Direct Comparison
R$ 3.500 – 5.500
- Local warranty, ready to use
- Domestic tech support
- Higher price
- Less config flexibility
R$ 4.400 – 6.100
- Parts flexibility
- Scarce and expensive barebones
- Higher final cost
R$ 3.200 – 3.450
- Best cost-benefit
- Access to exclusive models
- No local warranty, delays
- Customs risk
Conclusion
For the desired configuration (i7, 32GB , 512GB NVMe ), the analysis shows that buying everything in Brazil to build costs more or is equivalent to buying pre-built. The most balanced recommendation is: look for deals on pre-built mini PCs with 16GB RAM (R$ 2,500 to R$ 3,500 range) and upgrade the RAM to 32GB yourself (~R$ 1,400), totaling R$ 3,900 to R$ 4,900.
