I bought two of these for a specific project but I liked them so much that I'm now re-building all my touring PCs into these cases. The problems I've encountered are 1. Noisy stock fans which I replaced with quieter ones and 2. the metal plate that runs across the front hit the CPU cooler (a BeQuiet LP) and the graphics card (Firepro WX7100) so we used a Dremel to cut chunks out of the metal. Minor issues aside, I really like this case!
The item overal is made well, although the fans that come stock are silly loud, and you should 100% replace them ASAP. as stock, this real is not a case for using in the same room as the computer. however, it was really easy to remove what I didn't want from the case and put my own (ghetto looking af) front, which not only allowed me change the fans for something quieter, but also bigger (2x140mm fans), and now it runs really quiet. Overall, I really like the case, but it took me a lot of work to get it to a point i was happy to use it with.
This case was to hold an old i7 full ATX motherboard for a server, pretty decent quality for the price. No instructions but not needed really, the fans are very loud so replaced those with Noctua ones. Delivery was quick and easy with DPD, overall very happy.
I am extremely satisfied with my purchase. I bought the X438L for building my recording studio PC in, and I was looking at other rack chassis from well known manufacturers, but a lot of them are mainly intended for server use (meaning ridiculously heavy, deep and just ****** expensive). The X438L fit my needs perfectly. The price seemed almost too good to be true, and because of that my expectations weren't too high. But after completing the build I can only say that the case is built like a tank and is really easy to work with. A huge bonus is that all the included screws are magnetic (the horizontal orientation of the case makes dropping screws a complete nightmare otherwise). The shipping was really fast as well (and I'm based in Sweden!). My one complaint would be that the included fans are a bit noisy, but after monitoring my system temperatures for a few days it turns out I don't even need them. Just plain awesome!
