Good day all. I wanted to know if I can move the insides of my SX2800 pc to a Antec 300 case. My main reason being my video card (HD4650) gets hot 82deg when playing games. I would also like to upgrade my psu. My question is would this fit? Has anyone ever tried moving the insides of this pc to another case? Any tips on choosing the type of PSU and any tips or problems I might encounter doing this? Thank you very much any help would be greatly appreciated.
