Two buyers send the same one-line request to a mini PC OEM manufacturer — "10-inch-class small form factor PC, 16GB RAM, 512GB SSD, quote please" — and receive quotes that differ by 40%. Neither quote is wrong. They are answers to two different products, because the request never specified the fields that actually drive cost. A mini PC quote is only as good as the RFQ behind it.
This is the checklist we send to buyers before their first RFQ. Fill in all fourteen fields and quotes become comparable across suppliers; skip half of them and you will spend three weeks reconciling numbers that were never describing the same machine.
The mini PC market is fragmenting into verticals with very different Bill-of-Materials profiles. Healthcare workloads are growing at roughly 9.8% CAGR as telemedicine carts and imaging workstations replace towers, and those buyers pay for fanless aluminium chassis and validated thermal behaviour. Gaming-oriented units are growing at about 10.2% CAGR, which pulls BOM toward discrete graphics, vapour chambers and higher-wattage power delivery. Industrial buyers lean on wide-temperature parts, redundant Gigabit or 2.5GbE LAN and isolated COM ports for legacy PLCs. Consumer remains the largest single end-user segment at around 38% of units, but it is the most price-transparent and the least tolerant of BOM surprises.
On the architecture side, x86 still held roughly 71% of the market in 2025, while ARM designs are compounding near 9% annually as low-power silicon enables silent, fanless builds. That shift changes what "16GB RAM" even means: some platforms solder LPDDR at build time, which turns a memory configuration into a forecasting decision rather than a line item.
Add memory price volatility to the mix and an under-specified RFQ becomes a moving target. If your request does not state a price-validity window and a pass-through mechanism for DRAM and NAND, the quote you receive is an indication, not a commitment.
Name the actual job: office productivity, VDI thin client, digital signage playback, edge inference, machine vision, POS, or kiosk. This single field determines NPU and GPU requirements, and it is where most over-spec and under-spec originates. A signage player that only loops 4K video needs reliable sustained decode, not a discrete GPU.
Give a CPU family or a benchmark floor rather than a clock speed. State whether integrated graphics suffice, whether an NPU TOPS figure matters for on-device inference, and whether the workload is single-thread bound or scales across cores.
Specify capacity, type (DDR4, DDR5, LPDDR5X) and — critically — whether it is socketed or soldered. Then state how price movements are handled: a fixed quote valid for 30/60/90 days, or a pass-through tied to a named index. This is the clause that prevents the "memory went up, new price" conversation mid-negotiation.
Capacity, interface (SATA vs NVMe), and endurance class. For 24/7 logging or kiosk workloads, ask for the TBW rating and whether the SKU is industrial-grade with consistent supply over the product lifecycle.
State ambient range and dust exposure. Consumer fanless designs typically target 0 °C to 35 °C; purpose-built industrial units publish −20 °C to 60 °C or wider, with some rated −40 °C to 70 °C. If the unit goes into a control cabinet, an outdoor enclosure or a vehicle, say so — it changes the entire component grade.
Eight hours a day, 24/7, or intermittent? Duty cycle determines whether consumer-grade components are acceptable or whether you need long-life industrial parts and a validated thermal soak. A 24/7 deployment with consumer-grade cooling is the most common source of premature field failure we see.
List every port explicitly: video outputs and their versions (HDMI 2.1 with VRR/ALLM matters for signage and living-room use), LAN speed and count (dual 2.5GbE for network redundancy), USB-C with PD or Thunderbolt/USB4, serial RS-232/RS-485 for industrial control, GPIO, and audio. Legacy ports are usually the difference between a stock platform and a custom board — and the largest single driver of NRE.
Wi-Fi generation (Wi-Fi 6E/7), Bluetooth version, and whether cellular modem support is required. Confirm which certifications the radio module already carries for your target markets.
Form factor and volume, DIN-rail / wall / VESA mounting, and the noise ceiling in dB at full load. Sub-25 dB matters for recording studios, trading floors and healthcare; it also constrains TDP, which is why acoustics belongs in the RFQ rather than in a follow-up email.
Windows 11 Pro, Windows 10 IoT LTSC with its ten-year update cycle, Ubuntu LTS, or barebone. Industrial and regulated buyers increasingly prefer LTSC or Linux for lifecycle predictability. Also state firmware requirements: TPM 2.0, Secure Boot, watchdog timer, auto power-on, Wake-on-LAN, and whether you need a custom splash screen or locked-down BIOS.
List the markets and the marks you need: CE and FCC as baseline, UL for North American industrial installations, MIL-STD-810H for mobile and vehicle deployments, FIPS-validated modules for government work, plus RoHS and battery transport testing where applicable. Name who owns each filing — you or the factory — because that decision affects both cost and your freedom to change supplier later.
How long must the exact configuration remain available? Three years or seven? Long-life industrial components cost more but let you deploy the same image across a multi-year rollout. If you cannot commit, say so, and the supplier can propose a platform with a published roadmap instead.
Annual volume, order split, and target lead time. OEM builds on an existing platform typically start at 500 units, with ODM pilot runs available from 100 units. State whether you need staged deliveries, and ask what happens on repeat orders — a supplier with local supply-chain density can turn refreshed boards quickly, but only if the volume forecast is shared.
Define what "acceptable" means before production: PPM threshold, aging coverage, per-unit test log availability, and the remedy when a batch misses. This is the field most RFQs omit and the one that decides how a dispute ends.
The fourteen fields map cleanly onto three cost buckets. Platform fields (1–4, 8) move unit price directly and are usually where a 10–20% swing comes from. Mechanical and environmental fields (5, 6, 9) decide whether a stock chassis works or whether you are paying for tooling — the difference between a few hundred dollars and five figures of NRE. Compliance and commercial fields (11–14) decide risk allocation more than price, but they are what protect the margin you negotiated.
One structural note on sourcing: vertically integrated Shenzhen supply chains can undercut established brands by 30–40% because board population, chassis stamping and final assembly sit in one flow. That advantage is real, but it only survives if your spec is stable. Every late change re-opens lead time and pricing.
Once the RFQ is complete, platform selection is usually quick. For high-performance office and edge workloads, a compact high-TDP design such as our MX-APB03 high-performance mini PC covers most productivity and light-inference deployments. For 24/7 signage, kiosk and industrial control, the MX-APB04S mini PC is built around sustained duty and wide-temperature operation. If you are still deciding between form factors, browse the full mini PC product catalog and shortlist two or three reference builds to anchor the RFQ.
Because the request usually omits the fields that drive cost: thermal class, duty cycle, port count, certification scope and lifecycle commitment. A "16GB / 512GB" request can describe a consumer box rated 0–35 °C or an industrial unit rated −20 °C to 60 °C with isolated COM ports. Specify all fourteen fields and the quotes converge.
OEM builds based on an existing platform typically start at 500 units. Fully custom ODM programmes — new board, new chassis, new tooling — can often be piloted from 100 units, with NRE amortised over the production run. Both numbers belong on the quotation.
If the deployment is dusty, vibration-prone or runs 24/7, yes. Fanless designs remove the two most common mechanical failure points: the fan itself and the dust it pulls across the board. The trade-off is lower sustained TDP, so specify your performance floor in the RFQ rather than assuming silence is free.
Platform-based OEM builds typically ship in a few weeks once the spec is frozen. Custom ODM with new tooling adds design validation, regulatory testing and pilot runs — usually several months. The single biggest schedule risk is a spec that keeps changing after tooling starts.
Decide before signing. Factory-held certificates are cheaper up front but tie you to that supplier; buyer-held certificates cost more but survive a supplier change. Either way, name the test lab and the filing timeline in the contract.
Fill in the fourteen fields above and send them with your target market and volume band. We will return a written quotation covering BOM, MOQ, NRE where applicable, lead time, price-validity window and quality acceptance criteria — plus a reference build you can evaluate before committing.
