After a long time of thinking and struggling, I have decided to sell my Peli case.
It is a Peli Case 1740 and has the following dimensions:
Inner dimensions: 104.1 x 32.8 x 30.8 cm
External dimensions: 112.2 x 40.9 x 35.6 cm
Lid depth: 6.5 cm
Bottom depth: 24.3 cm
New this case is quickly 600+.
Bidding is always an option, send me a message.
Exchange is possibly an option if you have something nice of course :)
