First thing i see, Apevia PSU, no no! Get a good PSU that has Active PFC and is atleast 80+ basic certified, a cheap crappy unit does nothing but risk blowing the rest of your components.
I think you need to readjust a bit of your spendings, an AMD build would probably be a much better choice for you. A few questions first though, whats your total budget, whats the resolution of the monitor you plan on using? Also, why the multicard reader, and cheapo wireless card?
I'm assuming you picked a 'micro ATX' motherboard b/c htey are cheaper... but you don't want that. You want a regular ATX sized motherboard.
Id say go for an ATI 5770 instead of that GTS 250
I agree with Hunter, generally not a good idea to get a cheapo power supply, but since nothing you're looking at will use a ton of juice, I think you could get by on it if you really wanted to.
First thing, majority of these parts were suggested to me by a friend. He told me it would be cheaper to build a computer on my own than for me to buy it prebuilt.
hunter315 - I was planning to spend somewhere between $700-$800, give or take a bit. i will look for a better, not so cheap, power supply. the resolution of my monitor 1680x1050. I was actually planning on getting a different card reader and wireless card because they do seem pretty cheap, but it's what my friend suggested and I wanted to see what others thought first. Why would you say that AMD would be a much better choice for me?
lowriderflow - i picked the micro ATX motherboard because it's what my friend suggested and because it has USB 3.0. I'll see about getting the ATI 5770.
