I've pretty much locked in on the following hardware/software list. There are certain things that are probably overkill like the PSU but I have some reasons which I'll explain. I'm totally open to any and all suggestions, however, and am willing to entertain all advice.
Case: The case had to be good looking, roomy, and fit style-wise in my system. I wanted quality, but didn't want to spend $300 on some of the more esoteric offerings. Silverstone was the way to go as far as I could see. The GD07 is a really nice case that will look right at home sitting next to my Sunfire amp. It's got great reviews to back it all up.

CPU: The Intel i3 4130T has gotten great reviews from the HTPC community and seems to be the go to chip for current builds.

M/B: Layout of the board is important, especially with the case design and what you're going to put in it. The layout, the quality, the price... all make this a really good choice in my opinion.

CPU Cooler: I'm not sure I'm going to really need one, but they're not expensive so I'm gonna get one. I looked a ton of these, but figured the one from SilverStone is just as good as any and I know it'll work in the case and with my board fitment-wise.

RAM: This is my least sure choice. I think this okay, but just don't know enough. I know I'm going to stick with 4 gigs for now. I don't understand latency and timing and all that... not sure if it even matter for what I'm doing but I think these modules from GSkill are a good choice. The board has two slots. I'm just wondering if I should go with 1 4 gig module instead in case I want to bump up to eight if and when I decide to add tuner cards to the rig. I know there's a very small performance penalty but I'm not sure if it matters. I'm open to advice and debate on this.

PSU: I know 450w is overkill for this HTPC, but I wanted to go with a top performing PSU that was fully modular. I didn't see any modular options in the 350-375w range. SeaSonic seems universally recommended and I'm not opposed to spending a few extra bucks for a top of the line PSU

Boot Drive: SSD is a no-brainer these days. This Samsung has been reviewed to death and is regarded as a quality option.

Media Drive: For now I think I'm just going to use this box for video. My music is all perfectly setup on my other PC with PLEX. I'm just going to leave it like it for now. Once this is up and running, I'm going to build a much bigger NAS to store everything. That's just down the road a bit. For now, I'm just going to go with a Western Digital 3TB Green Drive which seems to be solid performer for an HTPC build.
Optical Drive: I'm going to upgrade my Blu-Ray reader in my other machine in my office where I rip my discs. I'm just going to go with a standard DVD drive for the HTPC just make software installation less of a hassle. I don't anticipate going in and out of the HTPC very often. I'll just rip on my other machine and move it to the HTPC over the network for now. It's just more convenient at this time. I'm just going to go with the OEM LG Blu-Ray reader... it seems as good as any.

OS: I think I'm going to stick with Windows 7. There's a lot more trouble shooting guidance on 7 then there is on 8. No other reason besides that.
Media Software: I'm going XMBC I'm willing to put the time and effort into getting this setup perfect. I want to be able to control things with my iPad and XMBC (as does PLEX) seems to have a nice enough remote app to run things. I'm going to set things up to boot right into XMBC so hopefully I'll just have to turn the box on, grab my iPad, and touch the screen to make movies happen.
That's pretty much the bulk of it. Again, if you see something glaring let me know. I did a lot of research on these components so feel free to ask questions if you have any. I'm going to hold off on ordering stuff just a bit longer to make sure I'm fine with everything. Once I feel 100% confident, I'll pull the trigger. You guys can help with that.
