Sûrement mon meilleur boitier
Le maître mot : compact ! De bonne qualité et montage facilité par son ergonomie. J'utilise une 4080 super MSI Ventus 3xc (seul modèle avec la Founder à être compatible avec ce boitier) Au top de la puissance, tout en silence. Posé sur le coin du bureau il en jette par sa sobriété. Très pratique pour le transport ou je frime devant les potes avec un boitier plus compact que leur console de salon. Je le connecte à un écran externe. J'utilise le cloud gaming désormais mais pour quelqu'un qui préfère avoir son propre support c'est le graal du boitier. Pour des raisons d'économie et de respect environnementale ça devrait selon moi devenir une norme chez les gameurs... Je recommande sans hésiter.

Hermoso case
Estéticamente el case es muy bonito, prácticamente no ocupa espacio en el escritorio, el estilo minimalista se acomoda perfecto a mis necesidades. Cabe perfecto un watercooler de 240mm y una RTX 4070 ti

High quality tiny case
Really nice case but don't kid yourself, it's a pain to build in this as there is little space. They've done some really great stuff to make it easier, like the removable mobo mount plate but it's still going to be tough. I would recommend the smallest video card you can find for a given GPU. I wedged in a 5070 of that type and it works great. I also managed to put a 2.5 inch SSD at the bottom for storage space. The mobo you buy should have at least one M.2 so the area they have for a 2.5 is gravy. Stick with SFF for a power supply. I know it will take the slightly larger SFF-L but if you're wanting to put a GPU in, it's best to avoid that. I've stress tested the CPU (AMD 9900X) and the highest it's gone is 53 degrees C. That's with all it's 24 cores (real and virtual) pinned to 100% for 10 minutes. I didn't bother letting it run longer because the temps just weren't rising. (CM MasterLiquid 240 core ii) GPU idles at 57 C. I haven't measured it while loaded because to play games I boot into Windows and that's all I use Windows for so am not interested in installing software to check it. In any case, it's given me no cause for concern. BTW, mine arrived with a damaged PCI-E riser cable (Pinched with exposed copper). I contacted Lian-Li and they had no problem sending me out a replacement which I got in about a week. That's service Ladies and Gentlemen and that's what you want. If you're looking for a powerful gaming computer with a tiny footprint, this is the case for you.

Un case di qualità.
Il case è abbastanza piccolo da stare sulla scrivania comodamente. I materiali interni sono robusti, i pannelli esterni si piegano un po' facilmente. Le viti non sono moltissime e sono quasi tutte identiche. L'aspetto è elegante e l'assemblaggio è fondamentalmente facile, ma ovviamente i cavi vanno modellati parecchio per farci entrate tutto. Temperature direi più che buone. Promosso, ma costoso.
