It´s been a while since I updated this thread so thought I would post the picture of my new homemade display cabinet
I disassembled my 3 IKEA Detolf´s and took the side glass and made them into shelves. The largest piece can hold around 340 figures each (3 lowest) and the smallest can hold around 250 each (2 top ones). It has allowed me to display all my figures, 782 pcs + convention (well, still have some at my Cobra vehicles

) and I have done so by year. I will need to make some small labels to place in front of each row so visitors can see which year is which and also sub teams like Python Patrol etc.
I also need to put all my Convention boxes at the top shelf but that will have to wait a few days.
Edit: replaced picture with latest one featuring all my convention figures.
