You two are fantastic. Many thanks.

There are cpus with no igpu that will work on a mobo with video outputs but the outputs wouldn't be usable.
Okay cool. The build you recommended has a motherboard with HDMI output, but also a discrete GPU, so I didn't know if I could connect HDMI via the motherboard and still make use of a discrete GPU without HDMI ouput. I assume this motherboard is a particularly good one if it would have this superfluous feature (HDMI ouput) if I attach a discrete GPU.
RE PSU: I went back to the calculator site and discovered that I misread how to count CPUs. I thought it said to count a quad-core as 4 CPUs, but I was supposed to count it as 1. That, not surprisingly, made a huge difference. Here is the site in case you are curious and can inform me if it is either way off or a decent guideline.

Looks like 300-400 will be plenty for me, and I can just edge closer to the upper bound to be safe in case I decide to upgrade anything later.
I'm still weighing whether or not I want an iGPU. I've used AMD in the past and was pleased, but that doesn't mean I am partial to them. Intel makes quality products. Given my research and your help so far, I have gathered that my options are:
1 - AMD with integrated HD GPU and motherboard with HDMI output, or;
2 - Intel with discrete GPU that has its own HDMI output and whatever compatible motherboard I want.
Option 1 is less expensive, and doesn't seem like it would sacrifice much in terms of picture quality for either Blu-ray movies or the very light gaming I plan on doing.
Option 2 would cost me a bit more, but *might* give me better graphics, even if only marginally. It may also leave me with greater flexibility for upgrading in the future should I choose to do so.
Do you two think I understand the tradeoffs correctly?
Not to go on and on, but I'm grateful for the help. It saves me the time of having to comb through a lot of barely related google searches to find the right answers.
