Selecting a processor, comparing graphics cards, optimizing your budget: designing a custom PC is a pleasure for the knowledgeable enthusiast.

TopAchat meets this requirement with a professional assembly service guaranteed in their Lyon workshop. Hardware experts retrieve your order, check each item, perform aesthetically pleasing cabling, install Windows 11, and subject the configuration to several hours of stress testing. The result: a PC ready to use which arrives at your desk double-boxed with internal foam padding. Note: Expert assembly is not limited to "custom" configurations. All Gaming PC by TopAchatAlready assembled in the workshop, they are shipped within 24 hours.
Furthermore, all configurations created via the Configomatic can be ordered with optional assembly.
TopAchat offers two formulas :
- Standard PC assembly
- VIP PC Build, which adds prioritization to the chain as well as sending all the component boxes.
Regarding delivery times: the company highlights a delivery time variable, depending on workshop workload and parts availability. Pre-assembled PCs ship within 24 hours, while custom-built PCs typically take between 5 and 10 days, sometimes less depending on the configuration.
For a one-time fee of €99,99, you delegate the risks of improper thermal paste application, a short circuit on startup, or a recalcitrant BIOS. Instead of spending your weekend diagnosing a black screen, you dedicate your time to harnessing the power of your new system.
Step-by-step assembly: from receiving the parts to shipping the PC
Before a screw is tightened, the workshop follows a precise procedure inspired by the electronics industry. The objective: eliminate any point of failure and deliver a stable system from the first power-up.
Control of the order
The parts are first scanned to ensure nothing is missing from your order. The BIOS or UEFI is updated if the motherboard requires it to accommodate the latest generation of processors. This step is especially important when using a custom PC design tool like the Configomatic.
Assembly and cable management
Thermal paste is applied according to the manufacturer's recommendations; the fans are positioned to optimize airflow and reduce noise. Cables are optimally organized to facilitate maintenance, improve airflow, and achieve a professional look inside the tower (especially if it has a glass side panel). Photos of the builds can be seen on the... Official Tumblr, demonstrate a particularly clean work.

Load testing
Each PC then spends several hours on a test bench: CPU/GPU load, memory and storage checks, temperature monitoring. Any deviation triggers an immediate return to the workbench.
Packing and shipping
Once validated, the machine is secured in its tower using expanding foam, then placed in a double-walled cardboard box. The original boxes can be included if you have chosen the VIP option.
