First, JEDEC isn't Intel...
Getting stock voltage memory is good because it will in 99,9% of all cases work (yes, I value this highly), not to mention that it's usually a bit higher standards since it runs at lower voltage some "hardcore" overclocking memory that violates pretty much everything.
I never mentioned RAID (which your motherboard also has) but I am a bit concerned of the small heatsinks and cheaper component layout (capacitors etc) since it's a small difference in price considering overall lifetime.
Even though I see your point and agree with it somewhat there has been nothing to show that 2 vs 3 platters have worse reliability compared to each other. 5 platters is questionable but there are no conclusive results AFAIK. I'm still claiming though that 1TB is the sweet spot and I presume he'll keep his computer for a while so no worries there.
You didn't mention overclocking nor did you mention E7200. It's quite a bit slower and will hinder video performance even with a beefier card (4870 vs 4850) as the article shows. E8400 provides quite a bit better performance at stock speed it can apparently hit 3,6Ghz without any major issues (googled it) which will still provide better performance. But then again, overclocking can hardly be recommended for a novice nor does it guarantee that he/she/it will hit the 3,6Ghz or whatever mark that's said and it may give nasty side effects. But then again, I don't encourage overclocking at all and if you need to start overclocking components to achieve desired performance you have clearly built an under dimensioned system from the start.
