I want to fit an Power Color RX580 in there. While it still fits with the drive cage, It is kinda to tight.

I also going to upgrade the PSU to a 

SilverStone Extreme 500 Bronze EX500-B 500W SFX

(Please ignore that the text is very big. Thats what happens when copy pasting 😉)

The psu should fit but securing it might be a challange.

I just want to remove the Thing for the Big drive cage and the small drive cage. Thanks!

(sorry my english is not that good)
