I ordered the wrong part but it's that beautifully made I didn't send it back

So am I giddiness to purchase further products from Bykski, I accidentally ordered the wrong water block for my CPU. However when it arrived I was absolutely blown away by the products quality finish fitment and design. To the point that I didn't want to send it back and instead give it to a close friend to use in his system and sure him just how good the products are from Bykski.

The acrylic has amazing clarity, the machining is absolutely gorgeous now that may seem geeky but I come from a world where billet parts or CnC'ed parts, can be make or break. The overall finish is beyond stunning. The paint to finish the outside of the block itself I couldn't tell if it was a matte textured powder coat or if the metal had been leaned, then coated. The finish is so uniformal it is beyond that of most expensive parts in the car industry.

Since then I have purchased more equipment from this company and I will continue to do so.

As good as any but better price

Took a chance with a less expensive brand. I bought the CPU and a 4090 Strix GPU waterblock. Both work great and saved a few bucks in the process.
