Great guide, mechBgon. I'll be using this soon to build my second rig; the first I put together in 2001 and have forgotten much of the process. Yep, 'time' itself noobed me. Again.
I liked the pictures of the screw threads. I liked the on-edge shot of the mobo showing the need for standoffs. As I read the initial portion about standoffs I wondered how you knew which holes to put the standoffs in? Initially I also wondered why you thought the "outie" standoff was a good idea because I didn't remember the mobo being like a wet bar of soap in the case, in need of restraint. However, later I learn of the EMI prongies.
I had a Very Audible Laugh <VAL> with your words regarding how to tighten down the mobo. I won't spoil the fun for others by alluding to it further.
On a separate issue, you write,
	
	
		
		
			In all cases, plug the first drive into the far end connector, not the middle one. Vacant sections of cable can cause signal bounce.
		
		
	 
...I wonder if "in all cases" should say "in all instances"? Just for clarity's sake. I got bungled for a moment here.
...Additionally, I was initially confused by these two sentences of yours but figured it out after a few minutes. My confusion stemmed from believing the first sentence wasn't compatible with the information in the second sentence. Allow me to demonstrate: a cable will have 3 connectors {all the time?}, one at each end and one in the middle. The first sentence plainly tells me to utilize the connectors at either end of the cable, eschewing the middle one. Okay, good. The next sentence tells me vacant sections of cable can cause signal bounce... uh oh, I left that middle connector vacant, I'm gonna get signal bounce; better re-read the first sentence. Re-read first sentence, still feel its plain to understand. Re-read second sentence, still feel I'm getting that one, too. Something isn't right, click pictures, re-read, click pictures, re-read. WTF? Nobody else mentions this in the review, so its gotta be me, what am I not understanding here, its gotta be something easy? Then something clicked and I understood you meant that *had* I used the middle connector then there would be a vacant section of cable with a vacant connector, the one at the tail end of the cable. Made for a frustrating 5 minutes. 
This is a pleasurable and informative guide, thank you for providing it.
