I have three aging Lian-Li cases that are holding up great these past ten+ years, with the only exception of these plastic connectors PT-JT01 for the front panel. For longer than I'd like to admit, I had a large rubber band holding the front cover sorta in place until I found Cooler Guys offering reasonably priced replacements. Two of my cases are silver, and one is black. All three have had at least one of the female side of the plastic connectors become fragile over time, breaking when removing for air intake cleaning. I wasn't able to mix old (male) and new (female) as they didn't line up perfectly when I tried, but using a pair as provided works great. I'm very happy the face plates are flush and snug like new.
