Thanks for the great tips!!
The Puget review is indeed one I used as inspiration to select my components
I might just as well get the Haswell right away as you suggested, so I've adapted my configuration a bit, changes in bold.
Case: Antec Midi Tower P183 V3 Performance One ATX
PSU: Seasonic Platinum Series FL2 460W, Modular, Passive (FANLESS!)Main board: Asus Z87-Pro iZ87, SATA600 RAID, USB3.0CPU: Intel Haswell Core i7 4770 3.40GHz 8MB Box
CPU Fan: Gelid Solutions Processor Tranquillo Rev.2
Memory: Kingston 2x4GB, DDR3, PC12800, CL9, HyperX
Storage: Samsung SSD 2.5", 256GB, SATA600, 840 Series Pro (Further storage is on NAS)
I made a concession on the CPU (4770 instead of 4770K) to keep the price down, compensating for the more expensive main board. I don't intend to overclock anything.
I could consider the Scythe Mugen 3 cpu fan but its specs say its noise level can go up higher than the Gelid Tranquillo? So I'm a bit cautious unless consensus here can reassure me it's better and noise won't go up
I couldn't really find good alternative PSUs in the webshop I'm buying from, and I admit the fanless idea is quite appealing. If things get too hot, I may later consider adding a slow front case fan as suggested. I also found this thread viewtopic.php?f=6&t=62501
which discusses precisely the case/PSU combination I'm considering. The impression I get is that it should be ok, also considering I'm not drawing so much power anyhow.
