    Perfect with AMD Ryzen 5 7600

    It has everything I need for my configuration and for future upgrades.
    Great for the AMD Ryzen 5 7600 Wraith Stealth (3.8 GHz / 5.1 GHz)
    A nice ergonomic bonus with the handy M2 memory lock system.

    Listening / Advice / Sympathy

    A great discovery, the LDLC Henin Beaumont shop, we wanted to offer a PC for our teenager but we had no computer knowledge apart from the basics... we were well received, listened to and advised, so this request for information was transformed into an order form and a week later the project was ready, much to our teenager's delight... different payment options depending on requirements are a plus.
    The guarantee, the advice, the explanations from competent people are top notch. We highly recommend LDLC.
