You've been looking for a gaming PC or an AI workstation in the region, and you've found either Amazon prices inflated by platform commissions, or 3-week delivery times, or a vendor unreachable once you have a problem after purchase.

We know this frustration well — it's exactly what prompted us to create Radiance Systems in Auriol, Bouches-du-Rhône. Since we started assembling custom PCs for customers in the PACA region, we wanted to write the guide we would have liked to read before starting: an honest comparison, concrete criteria, and our own field feedback after hundreds of configurations assembled.

Whether you're looking for a gaming PC under €1,000, a workstation for video editing, or a PC capable of running local AI models for your firm or business — this guide is for you.

What makes a "good" PC builder in the Southeast? The 5 criteria that really matter

Before comparing offers, you need to know what to compare. Here are the 5 criteria that any serious buyer should check before placing an order.

1. Transparency on components

A good builder provides you with the complete list of parts before purchase: CPU brand, exact GPU reference, RAM brand and frequency, SSD brand. Beware of vague product descriptions like "high-performance GPU, 16 GB RAM" without any reference — it often indicates low-end components or unknown brands.

2. Local vs. national after-sales service

Sending a PC for repair from Marseille to a Parisian warehouse is at least 10 days round trip. A regional builder can handle your problem in 48 hours, or even meet you in person if you live nearby. This is a huge advantage that many customers only realize at the first hitch.

3. Manufacturer warranty vs. seller warranty

The legal minimum in France is 2 years. But check if this warranty covers individual components (which is good practice) or only the assembled unit. At Radiance, each PC has a 2-year warranty, components included.

4. Pre-sales responsiveness: a revealing test

Send a technical question by email or phone before buying. If you don't get a response within the day during the week, it's generally an exact reflection of what the post-purchase after-sales service will be like. At Radiance, we respond in less than 3 hours during working hours.

5. Auditable config/price ratio

Take the proposed configuration and compare the price of each component on LDLC or Materiel.net. The acceptable assembly margin for a mid-range PC is between €80 and €180. Beyond that, you're paying for the brand or the distribution channel, not for the quality of the PC.

Comparison: PC builders in the Southeast in 2025

Here's an objective comparison of the main options available for buying a PC in the region:

Criterion Radiance Systems (Auriol) Major Retailer (Fnac/Darty) Marketplace (Amazon/Cdiscount) Independent local builder
Price ⭐⭐⭐⭐⭐ Guaranteed lowest ⭐⭐ Intermediate margins ⭐⭐⭐ +10–15% platform fees ⭐⭐⭐⭐ Variable
Custom PC ✅ Full configurator ❌ Fixed stock only ❌ No custom builds ✅ Yes but long lead times
On-site pickup ✅ Auriol (13390) ✅ In store ⚠️ Depending on provider
Local After-Sales ✅ Priority in-person ⚠️ Centralized After-Sales ❌ Warehouse return only ✅ Yes
Delivery time 4–10 working days 3–7 days 2–5 days 7–21 days
Warranty 2 years included 2 years legal 2 years legal Variable
Technical advice ✅ Directly with the builder ⚠️ Generalist salesperson ✅ Yes
Verified reviews 4.8/5 Trustpilot (100+ reviews) Variable Variable Few or no reviews
AI PC / Workstation ✅ Dedicated range ⚠️ Limited ⚠️ Depending on skills

Major retailers have the advantage of brand recognition and sometimes faster delivery times. Marketplaces remain competitive on logistical responsiveness. Radiance wins on net price, customization, after-sales service, and technical expertise — especially for high-performance gaming configurations or professional AI PCs.

The most requested PC configurations in the Southeast

What customers in the region are looking for is not so different from the rest of France — but the Mediterranean climate and local economic fabric create some specificities that any good builder must know.

The 18–30 year old gamer — budget €500 to €1,100

The most sold configuration in the region revolves around a Ryzen 5 coupled with a mid-range GPU. At Radiance, the Vega 7 RGB (€572) and Aqua (€958) models are bestsellers. An often-overlooked point: cooling.

💡 Pro-tip from the field: In summer in Marseille or Aix, ambient temperatures can exceed 30°C in an unairconditioned room. We systematically recommend a case with at least 3 fans and quality thermal paste. This is included in every Radiance configuration — not a paid extra.

The professional/creative — budget €1,200 to €2,000

Video editing, 3D rendering, architecture, graphic design: these uses require VRAM and fast RAM above all. An RTX 5060 Ti 16 GB + Ryzen 7 or Intel i7 configuration covers most professional software. Example: the Radiance PC RTX 5060 Ti 16 GB - Intel I7 14700F at €1,741.

The liberal professional looking for an AI PC — budget €800 to €3,000

Lawyers, doctors, accountants, consultants: the demand for PCs capable of running LLM models locally has exploded since 2024. The challenge is simple — process sensitive client data without sending it to foreign cloud servers (RGPD compliance). Radiance offers a dedicated AI Station range designed for this purpose.

How to order a custom PC from a local builder: 6-step guide

  1. Define your actual use. Ask yourself three concrete questions: what games or software will you use? What resolution will you play or work at? What is your maximum budget? There's no need to pay for an RTX 5080 if you're playing at 1080p — an RTX 5060 will be more than enough.
  2. Get a personalized quote. Contact the builder with your use and budget. A good builder responds within 3 hours during the week. At Radiance: online form, phone at 04 65 84 48 21, or live chat directly on the site.
  3. Check the component list. Demand a detailed sheet: CPU brand, exact GPU reference, RAM brand and speed, SSD brand. Then compare prices on LDLC or Materiel.net to confirm that the margin remains reasonable.
  4. Validate and order. Use the online configurator or finalize by phone. If you need to spread the payment, payment in installments without fees is available online at Radiance — it must be made at the time of order.
  5. Monitor assembly and testing. Your PC is assembled, stress-tested (CPU + GPU), Windows installed and activated. Allow 2 to 5 days depending on the complexity of the configuration.
  6. Pick up your PC. Colissimo delivery anywhere in France, or on-site pickup in Auriol (13390) by appointment. In case of problems after receipt: after-sales service is available by phone, email, or live chat — free return with Colissimo label provided.

AI PCs and workstations in the Southeast: demand from PACA professionals

Since 2024, we've been receiving more and more requests from liberal professionals — lawyers, doctors, accountants — who want to run artificial intelligence models directly on their PCs, without sending their data to the cloud. This is a fundamental trend, driven by RGPD obligations and the increasing maturity of open-source LLM models.

What a local AI PC requires

  • GPU with at least 16 GB of VRAM (RTX 5060 Ti 16 GB, RTX 5070 or higher)
  • System RAM: at least 32 GB DDR5 to avoid bottlenecks
  • Fast NVMe SSD for model loading (files weigh between 4 and 15 GB)
  • Well-ventilated case — GPUs in AI inference heat up more continuously than in gaming

🧪 Tested in-house at Radiance: on our demo server equipped with an RTX 5060 Ti 16 GB, we run Qwen3 14B, Mistral Small 3.1, and DeepSeek-R1 14B (Q4_K_M quantization via Ollama) without problems. Result: between 15 and 25 tokens per second — sufficient for daily professional use.

Which GPU to choose for local AI?

GPU VRAM Compatible Models Typical Use
RTX 4060 / RX 7600 8 GB Quantized 7B models Experimentation, light use
RTX 5060 Ti 16 GB 16 GB 7B–14B models Solo professional use ✅ Recommended
RTX 5070 12 GB 7B–13B models Balanced Gaming + AI
RTX 5080 16 GB Models up to 30B Intensive AI Workstation

Why choose a local builder rather than a national order?

The honest answer: not for all cases. If you want a basic PC delivered in 48 hours, Amazon may suffice. But for a custom configuration, professional use, or simply peace of mind regarding after-sales service, a local builder has strong arguments.

💡 Our story with Amazon: we started by selling on the platform. Fees exceeded 10% per sale, which forced us to increase our prices to maintain margins. We stopped in mid-2024 to sell exclusively direct — concrete result: more powerful configurations for the same client budget.

💡 On-site pickup, an underestimated advantage: the customer sees their PC boot up before leaving. We perform the startup and performance test in front of them. No possible dispute over the PC's condition upon receipt.

💡 Local after-sales service really changes everything: a customer from Marseille or Aix with a problem on Monday can pick up their repaired PC on Wednesday. No national builder can offer this turnaround time.

In summary, the concrete advantages of using Radiance Systems:

  • Prices without marketplace commission or physical store overheads
  • Pre-purchase advice directly with the builder (not a call center)
  • Local pickup in Auriol, 13390 — 20 min from Marseille and 25 min from Aix-en-Provence
  • Priority on-site after-sales service for local customers
  • 2-year warranty on all PCs, free Colissimo return provided
  • 50-day no-questions-asked return policy
