Customer Reviews
This is a beuatiful and really easy-to-build case. Once you have everything you need to build on your hands you can finish it really fast. I have only 2 "complains":
1. I wish it could have in-built USB connectors and/or audio jack.
2. The inlet ports at the back of the case doesnt align with most of the commercial radiators. It is really hard to install any other radiator different than Bykski with hard tubbing. I recommend to use soft tubbing instead.
Other than that, this case is just awesome.
If you are liquid cooling your system and want the best aesthetics with the simplest setup, this is an easy call if you have the cash for it. Open air design with liquid cooling offers the lowest temps.
I am really surprised with the quality and performance of the Bykski brand.
I got the G20 Case, the GPU Full Cover Block 4080, pump, fittings, extenders and quick release valves.
Since in Brazil we don't have the Bykski stores, I had bought the CPU Water Block (for I9 14900K) from Bykski throught AliExpress. Unfortunately, the transporter lost my order during Christmas and I am in a process of refund.
Congratulations for the brand and for the work.
Seems to be working so far no hiccups
Waiting for missing screws. Fantastic Customer Service easy to talk to fast response. Would recommend Byskski.US.
We're sorry for the oversight and happy our team could help you take care of the issue!
Before you install it
This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.
