My pc is a dell optipex 7010 dt . It comes in a low profile case and I found out that it only has a 50 watt gpu slot. As the gpus I want to use require more power than that I would like one with a 6 pin connector. The only problem is that lp cards don't come with these. So I am wondering how easily transferable my parts are to a new pc box. I get the psu wont fit properly but I need to buy a new one anyway but will the motherboard/hardrive fit?
