Hi, just got a versa h15 but there is no space for the dvd drive with a mATX full lenght mobo (Asus Prime B450M-A).
I used the shortest dvd drive i could find, a 165 millimeters drive by LG
The dvd drive cover the mobo for about 15 millimeters and the dvd power connector press one of the dimm.
I had to mount the dvd drive protuberant the case.
To TT engineers: you should specify this limit for this case. You could avoid this troble simply increasing chassis lenght by 20 millimeters.
