I plan on using this with a radeon 6670 1gb ddr3 (or if you have any recommended GPU within $70- $100 price range.)
Im new so im also wondering if the Motherboard being micro atx does that mean the PSU and Case have to be micro atx too?
I'm personally not caring for your power supply choice here, mostly because of this article by HardOCP http://www.hardocp.com/article/2009/02/16/entry_level_p...
linked to the conclusion page - perhaps a Corsair CX500?
And no. your PSU should be standard ATX, your case can be any size that can fit micro-ATX (virtually all)
