Thanks very much for your suggestions!
How much storage do you intend to use? Without so much hard disk space being used a larger SSD and no HDD would be better. A 256Gb is not so expensive now and in future SSD prices are going to get better and better so if you run out of space you can easily buy a second one without adding any noise and very little power, space, heat and cabling.
Certainly I'll need more than 256Gb, but maybe I'll think about getting some external drive instead.
This is somewhat over powered for the system which will probably be ~100W max. Super Flower unfortunately only go as low as 400W in 80+ Gold or a Seasonic G360 would make better sense.
I chose it for Platinum, but perhaps it's not that important with so low power usage?
Perhaps over the top size wise for the components you are putting in it and the associated power draw. Consider the Antec NSK3480 and use it's included PSU instead. This will save a lot of money.
I like the look of Lian Li much more, plus it has USB 3, but I'll think it over again.
I wouldn't bother with the S part. The non-S part will use the same amount of power at idle and your low loads. If/when you need the processing power at high load, the non-S part will just finish the task sooner, consuming similar or potentially less energy over the time used.
The reason I'm considering this model is HD 4000 graphics. I don't know if I benefit from it that much (compared to HD 2500) though. What do you think?
Intel 330 60GB: or you could spend maybe $20 more and get a 120GB Samsung 840.
Right. I can buy KINGSTON V300 120 GB even a little bit cheaper - which one should I chose?
