I need some help deciding on both a case and a power supply(mid-range price), as i don't really have any experience in these two areas. Also, as i said this is my first build, and I believe everything is compatible, however if you spot any potential problems please point them out.
Buy a 600w or 650w Bronze certified PSU. Antec, Corsair...
I guess I hadn't noticed the SPIKE in HDD prices but that price seeems High.
Try to get a 560 Ti
Antec 300 case work s well but most mid-tower cases in the $60-$100 range will be fine. Note the no. of fans you get and where they are located. I'm a firm believer in top ventilaton.
