The presented model was designed for Xigmatek Mini-ITX PC case with the part number CCD-02ABX-U01 (link). The design of the original LED cover allows for the installation of GPU's with maximum length of 200 mm. The attached modified LED cover makes it possible to mount GPU's with length exceeding this value. Of course, just by disassembling the original cover, we get the opportunity to install longer GPU's, so it's a more “nice to have” modification to keep the PC case in the set. Anyway, I suppose it's not a very popular PC case, and I guess it was discontinued quite a while ago, but maybe someone will still find it useful.
The author marked this model as their own original creation.
