Billy bookcase + some bolts.
OR remove Dvds from boxes, put into flight case. Cover wall with dvd case flat facing out somehow "for that arty look"
If you have access to a storage area, like a loft, then just put all empty dvd cases into a box, store it in the loft, leaves you loads of room to keep the dvd's in the flight case. Couldn't tell from the picture the type of dwelling you live in, so i couldn't tell if it was your own house/parents/uni halls/general digs.
