[WaxWeazle]

I pledged earlier for it on Kickstarter for this;

CYBORG ENFORCER
+ Big Box Collector’s Edition:
? Soundtrack
? Tri-Optimum Handbook
? Tri-Optimum Crew Patch
? Tri-Optimum Crew Pin
? Repair-Bot Figurine
? Steel DVD Case with the Game (PC)
+ Cyborg Enforcer Forum Badge
+ Cyborg Enforcer Credit In The Game
+ Exclusive Access to Developer Forums

You will also Receive:
+ Digital Collector’s Edition (Choice of Supported Platform)
+ Exclusive Access to Closed Beta (Steam)
+ Digital Copies of:
? System Shock Enhanced (2015) (PC)

So seeing it says DVD case, I'm going ahead and say it'll be a DVD case
