    Fully satisfactory in every respect

    No bad surprises: with 4x8Go of RAM (salvaged, but 16Go is enough) and an R5-5600, it lets me upgrade my old PC to W11. The bios update is very simple (just the motherboard and the PSU and a USB key, no need for CPU or RAM for this step). Ideal for small DDR4 budgets that don't have extreme needs or a recent setup.

    very good value for money

    I wanted to upgrade my old PC (MSI Z170, I5 6600K, GTX 1060) and keep my DDR4 memory (given the current prices).
    Paired with a 5800X and an RTX 5060, I am very satisfied with the performance for a reasonable price, and not being a PC gaming expert,
    I can only recommend it. What's more, having already dealt with LDLC's after-sales service, I can sleep soundly ;-)
