Pretty solid upgrade for the price, I love the see-through, but you don't end up seeing very much through it. The product photos do show the look pretty clearly. The purple does not stand out very well in dim lighting (or screen only lighting)
I ended up mixing the purple base and frost keyset and the combo with the lighting is just amazing. Will get a photo up eventually.
I first tried out the drop purple skylight keys with this and the backlighting looked terrible. Legends were very hard to read so I don't recommend that even if it looks decent with it.
I bought the frosted edition and was very excited to get it. I already had a custom PCB & foams from AliExpress that had both Per-Key RGB and Under glow so it would've been perfect for this. However, this really only works as intended, for owners of a CSTM80 only. I understand that it doesn't include the weight or gaskets of the CSTM, but it didn't even have case screws. I mean c'mon. Case screws are standard for ANY case on the market, be it replacement or not.
This case is excellent quality for the price. It is only slightly frosted so you can easily see the components under the case. Feels premium for the price. Highly recommend.
