You could perhaps buy a cheap itx case for now and then buy the ghost when it becomes available. If you’re on that close of a time crunch for school I don’t think I’d want to take my chances. You can buy a few decent quality cases for under $100 such as the Silverstone SG13

Order it close to the drop of the ghost and if you happen to get ghost in time, you can return the SG13(for example) within the return window
