Case - Nofan CS-80
Aesthetics are obviously a personal thing on cases. There should be plenty of ventilation here to allow passive running for a low power build but maybe it is worth considering a heatsink case like a HFX or Streacom instead? This has dust sealing advantages and keeps buzzing components separated from your ears.
PSU - Silver Power SP460-FL 460W (made by Seasonic X-Series)
460W is an awful lot for a system that will use maybe 100W max. You are unlikely to ever be able to expand your TDP up to that kind of power level and keep passive cooling throughout so you might as well save some money and go for a 400W PSU instead - or even a small low power PicoPSU or similar.
CPU cooler - Nofan CR-95C Pearl Black IcePipe 95W
The jury is still out on these things. Yes, they are passive and should be able to cool one of the 84W CPUs without much problem but they have a lot of physical constraints and are hugely expensive. Perhaps a Thermalright HR-22 is another option, there's a few others too. Or maybe look at a Heatsink case.
Motherboard - Gigabyte GA-Z87X-D3H (LGA 1150)
Why go for a fullsize ATX motherboard? Unless you expect to use lots of expansion cards or multiple high end graphics cards there is no point. You will slightly add to the TDP, cost and risk of buzzing components just by having something bigger. Try MicroATX instead.
I've seen that Haswells generate more heat than IB and obviously wanted to avoid heat buildup (esp for the more CPU-intensive multi-threaded tasks) so was thinking either i7 4770T or i7 4770S because of the hyperthreading and performance. Or would a 65W i5 be better?
S and T versions can be matched for TDP by simply undervolting and underclocking a standard CPU if you want to save money. In terms of i5 versus i7, what are the hyperthreading requirements of your applications? If not beneficial, an i5 is obvious. IIRC the higher TDP is partly down to the improved iGPU which may not be so much of interest to you and if you're only working on the desktop, shouldn't make a huge difference to power in use.
