Thank you all for your help. I was actually looking for something smaller for the living room as I wouldn't be doing any gaming with it (already have an XBOX/PS3 - although it's not comparable to PC gaming, it gets the job done :-) )
I ended up not building anything myself. After I priced everything out (including getting a nice case for the living room) I'd have to spend roughly $600-700.
I ended up picking this up at my local Fry's. They had it on sale for $399.
It has everything I needed. Although the motherboard is not anything amazing, it'll get the job done for what I needed it for (with the HDMI out.) For $399, I consider it a steal. It's about the size of my XBOX 360, so that's a definite plus.
I also ended up picking this up in the process. I'd recommend it to anyone looking to build an HTPC setup. Best part is, no keyboard/mouse in the living room.
