I'm building myself my fist home built desktop and can't decide whether to get this mobo http://www.newegg.com/Product/Product.aspx?Item=N82E168... or this one http://www.newegg.com/Product/Product.aspx?Item=N82E168... . My other parts are going to be an AMD Phenom II 965 Black Edition Deneb, and a EVGA Geforce GTX 550Ti. Also, I don't know if the Asrock mobo will fit in my Rosewill Challenger mid atx case and if the ASUS will be too small for the video card. Also, which one has better performance, quality, and will work better with my other parts.
Forgot to ask, since I'm making a new thread I might as well ask if a Corsair builder series 430W psu will be enough to operate all of this and the three fans(2 120mm's and one 140mm) that come with the Rosewill case.
I like the Asrock ATX board over the Asus microATX because it has an AM3+ socket for a bit more future proofing, SATA 3, USB3, and a newer chipset. But don't waste your time trying to use the x4 PCIe slot for a 2nd graphics card. While lots of folks feel Asus is a bit higher up the food chain than Asrock, I feel Asrock is fast becoming their equal.
Your case will accept either board with no problems. Either board will accept any PCIex16 graphics card. As far as the PSU, you should be fine. But here's a PSU calculator for future use: http://www.thermaltake.outervision.com/
As long as your case is atx format, the new board will fit but it may be tight. For the video card, measure your case from the video slot to the drive cage, allowing for some overhang from any standard sata drive. I like the side facing drive cages for this reason, but I don't have your case pics for reference. I would go with this power supply if funds are tight: Rosewill green series RG630 watt for $49.99 after promo code (link doesn't work). It gets good reviews and has 50 amps on the 12v rail, which is much better than the low end corsair.
Thanks for the help. I am not planning to ever go with a second graphics card on this system. Also, I think I worded it wrong, I didn't mean for it to sound like I already have the case, I am actually ordering it with the rest of my parts. So I am unable to measure the inside of it. But I do appreciate you showing me the Rosewill 630w, I do have 5 bucks to spare and will have to go with that.
