Note: My main problem is with the case, psu and mb. Will it suffice and also, I will not be overclocking, SLI, or anything like that. My budget is $800 and since I'm on a tight budget, I don't want to purchase things I'll not be using.
And yes I will need a HDD, sorry about that, I'll update it, but I already have Windows 8.1 64-bit OS and other main components not mention above. Also, since I don't plan on overclocking, I'm thinking(?) the stock cooler will be efficient. It's just that, I don't want to overkill the build as I'll be using my pc mainly for casual gaming, watching movies and listening to music. I am just wondering will it be okay to replace the PSU and Motherboard from the above build with the built I've posted at the start of this thread, as I can get my hands on both at a local dealer at a much lower price.
