I was doing pretty good until I got to the damn WD hard drives. I suspect I paid way too much for how good they are. Probably could have saved some money by making an enclosure and using real hard drives or something
Want quality? Your amp probably accepts a volt or two above/below 12v. Probably no need for a regulator as long as it's close. You could build a nice power supply with a 9v toroidal transformer, a full-wave DC rectifier bridge, and some capacitors. This would provide a little over 12VDC, as much amperage as you need depending on the VA rating of the transformer and size of the capacitors.
Or you can just buy one like this, which worked fine for me for Tripath amps... http://www.amazon.com/gp/product/B000VE7GQQ
(there are other cheaper prime eligible ones, not sure if they work as well).
Noctua fans will give you the best airflow-to-noise ratio, and most of them also have among the best static pressure (pressure that doesn't fluctuate because the fan blades are more closely packed together). Airflow is more important for case fans, and static pressure is more important for radiators.
They aren't cheap - around $25 each - but are excellent quality.
Another route you could go (which is certainly unpopular around this reddit) is to get a motherboard with a low-power, integrated CPU. There are plenty of options which include passive cooling. You said you only need basic office applications, so there's really very little need for much processing power.
Two more recommendations from me if you go this route: picoPSU combined with a DC power brick will reduce power consumption because a PSU has its own fixed overhead.
An SSD will also help you save a bit on energy, but will especially make the computer feel snappier as your programs load almost instantly. I recommend a Samsung 830 or 840 Pro (not 840 non-Pro). You can also do well with a Crucial m4 or an Intel 520.
If you use these parts, you can get your idle power consumption down to a mere 20W, which means you could leave it on all year long and pay only $20!
I like the M350 case. So, I've added in that case, a 90w PicoPSU and an AC adapter for an extra $80. Couple in the BT adapter, 360 wireless receiver and a 3.5" to 2.5" mount and the price of the whole build comes to ~$320 before shipping and any potential taxes.
However, I've heard some bad things about the AMD A1 platform, particularly surrounding driver support. So I've developed a competing build utilizing the Intel Celeron 1037U chip.
The cost of the build before accessories is ~$200. Add on to that a Kinivo BT 4.0 adapter ($13) and a 360 Wireless Controller receiver ($10) and the toal build cost would be ~$220 before shipping and taxes, a whole $100 cheaper.
I could also spend $70 on the M350 case w/ an 80w PicoPSU and included AC adapter, which saves me $10 over buying the three parts separately. It's currently out of stock and IDK if it will come back in stock anytime soon. Assuming it did, would the $10 extra be worth it for an extra 10W of power?
What do you think of this build in comparison to the AM1 build you proposed? I've dropped the Foxconn build now because of this build and the AM1 build.
I am building a proof-of-concept/prototype at the moment. Once I cobble it all together and confirm that it works, I will have to pay someone to design everything into a single PCB.
I was leaning towards this solution for the prototype:
