    The computer is very well assembled, the build time was way shorter than advertised, and the communication with Wessel is fast and very very useful. The thermals on the laptop itself are not great out of the box, so I would recommend going for the liquid metal thermal paste option (I had to do it myself after the fact and the difference is huge, the laptop doesn’t reach thermal throttling even under sustained stress).

    ## Full spec of order:

    – OS: Linux Mint 20.1 x86_64
    – Host: NS50MU
    – Kernel: 5.11.0-25-generic
    – Shell: bash 5.0.17
    – Resolution: 1920×1080
    – DE: Cinnamon
    – WM: Mutter (Muffin)
    – Terminal: gnome-terminal
    – CPU: 11th Gen Intel i5-1135G7 (8) @ 4.200GHz
    – GPU: Intel Device 9a49
    – Memory: 1716MiB / 64117MiB

    ## Physical characteristics

    Sleek and attractive looking, solid feel in a compact, nice metal case. The screen is bright, with vivid colors and a thin bevel. The keyboard feels solid and has good response without too much clickity-clack. The track pad also has a good feel and very responsive scrolling (esp. compared to previous Clevo – 4ish years old, which was clumsy and required lots of effort/force to move the cursor). The fans are quiet but effective – nevertheless, I recommend spending the extra money for the liquid metal instead of basic heat paste – the bottom of the machine becomes hot to the touch while charging. Despite this CPU and other temp sensors remain in the low-normal range during operation. It’s also possible to adjust cooling settings in bios according to your use needs. Sound is as to be expected for a laptop. Loud enough, but a little too much treble/mid for avid music listening – totally sufficient for video conferencing, Netflix or the like.

    ## System / software

    This configuration approaches one of the most out-of-the-box ready systems I’ve had the pleasure of unboxing. Mint 20.1 Cinnamon is perfectly usable as is and seems very stable on this machine. The graphics are cooperative, even on multiple screens, and the RGB-keyboard can be controlled with fn key+ without fiddling with any additional software.

    ## Service

    Wessel is patient and attentive to questions, usually answering within a couple hours. No issues with billing or invoices. My order was put together and shipped faster than indicated on the order form.

    Vorige week mijn nieuwe ubuntu laptop ontvangen. Het bestelproces verliep er goed en er is snel geleverd wat er besteld is. De bestelde laptop is snel en werkt goed. Wel vind ik de werking van de trackpad wat tegenvallen. Hij is wat stroef en af en toe reageert hij wat onzeker. Ik kom af van een luxe chromebook en die had een perfecte trackpad, dus ik was wel verwend. Nu toch maar weer op zoek naar goede muis. De overgang van chromebook naar terug naar ubuntu is wel weer wennen, maar tot dusver ben ik er blij mee. Het geeft toch een lekker gevoel om weer meer controle te hebben over je data en applicaties dan bij gebruikmaking van een chromebook en afhankelijk te zijn van google.

    Great service and great laptop! Delivered with expected timing, perfectly built.
    Also Wessel has been totally transparent in proposing a qualified alternative due to lack of a component which I originally ordered.

    Totally worth it, 100% recommended.

    Core i5 11th gen, 32 Go de ram, SSD pro 500 Go supersonique, du Linux et du opensource jusqu’au Firmware, le tout installé pour moins de 1100€. En plus de ça, le paiement par virement se fait en moins de 5′. Le tout arrive super bien emballé en moins de 3 jours. Un service multilangue dans un excellent français pour des CGU très claires. C’est une belle promotion du libre, c’est européen (ça va pas jusqu’aux composants, mais ça c’est l’étape suivante …), c’est évolutif et réparable (mais j’espère surtout que je n’aurais pas à voir si ça l’est). Ce site est vraiment bluffant.
    Après, juste un bémol esthétique : les écritures sur le clavier sont un peu grossières (mais on va dire que c’est “inclusif”) et ça rebondit un peu trop à mon goût (sûrement l’effet de la légère surélévation, comparé à mes précédents laptops). Je vais m’y faire et ça ne vaut pas une poussière d’étoile de moins.
    À faire connaître autour de soi !

    Core i5 12th Gen, 32 GB dualchannel memory, 1TB nvme SSD. The device is very elegant and modern looking. The keyboard has a bright backlight with a good variety of colors and feels very good for a laptop keyboard. Due to the newer Alder lake CPU the system consumes little power with lower loads, but performs pretty well under high loads. Also the received support by Wessel is very good, fast and helpful.
    Because the firmware did not pass some tests, I had the choice of waiting a little longer until the new release or receiving my unit right at the beginning of november which I chose. Since then, the correspondence with Wessel about some minor issues went pretty well and he was very helpful.
    Only issue may be that the device is running a bit hot when e.g. browsing Reddit while my older laptop just started hanging and lagging in those situations, so I’d just say it’s an optimization issue on the webpages side. But when running under sustained load with CPU temps from 60-80˚C, I’d recommend to put the device on a table (even just for better cooling) because that can become a bit uncomfortable. Also I’m impressed how cold the touched surfaces stay like touchpad, palm rest and keyboard when running so hot.

    Overall a very solid and performant, relatively compact and sleek device which I’m very happy with.
