"While we have the variant without an external drive bay, Cooler Master also offers the chassis without a 5.25" drive bay."

Uh that's a nope from me dawg.

You should double check the first page of the reviews. It shows the same dimensions for both the ATX and MATX cases.

As well as stating it has an external drive bay.
Yes I know there is that variant available, but as stated in the review they received the version without, yet all pictures clearly show the drive bay.
Despite those errors this is "cute"

The audio jack is most likely the same kind as on your phone, i.e. TRRS, rather than TRS, so as long as you have the right kind of headset, it'll still work.
As per the CM spec page - I/O Panel - Audio In / Out1x 3.5mm Headset Jack (Audio+Mic)

Also, you listed it as having 8 expansion slots.

Its a 4-pole jack. It does audio and mic

A 5.25 drive bay... I think I threw up a little.
