I registered for this forum just so I could thank you for your excellent instructions. I have an Obsidian 450D with a broken latch and was scratching my head.
I found another post with a broken link to the part, so no help.
In case your links die, folks can do a Google search for Door Latch for WFCO Converters (WF87/8900-DL)
I found one on Amazon for under $5 with Prime shipping. They are also available on Ebay and elsewhere.
Not sure if I have the patience to dismantle the front panel, I may try the forceful-tug-from-the-front method to pull out the broken one.
I find the latches not very intuitive. It wasn't obvious to me from just looking at the case that the panels have push-to-release latches. What we call push-push at work.
