On your rig description you stated gtx 660ti dc2, does that mean you are buying another 660ti? If you are upgrading at that price for the gpu i would say go for the 7950. Usually if you want a sidepanel you need to go to those custom case service to do it or you can do it yourself. Usually those services are really expensive.
Im Buying another 660 ti... I want to do it myself but there are so many ways so im confused
... I dont want to use a dremel or cut my case... I can remove the side mesh easily and fit in a piece of acrylic but there are these metal parts that stick out..
