Looking further, I'm not completely clear on what component has the Apple logo...
If it's just the drive tray that you have the optical drive mounted on, then it's a simple mix-up: someone tossed an Apple drive tray in it when it didn't belong. Looking further, those 5.25" drive bays are obviously meant for a standard "attach the metal rail on each side of the optical drive" type mounting - I've seen those a thousand times in many random chassis manufacturers over the years. With the side fan, this looks like your average early-2000s Pentium 4-era chassis.
And it almost assuredly had a cheap plastic front panel that is long since lost. (Hell, I have two old ATX chassis myself whose front panels are broken enough that they don't stay put any more.) Without those front panels, they all look remarkably similar to yours.
I think your Apple tray was a complete red herring. You just have a low-end ATX chassis from the early 2000s.
