Thank you vers much for the detailed feedback - another option which i did not consider is to go fanless on my bigtower (where i have the q6600 inside) as i wont move the pc much and i do have the space..
So an humble Pentium G3430 could be more than enough
I fully agree on that.
I'd look to the higher capacity variant of the proven Crucial M500.
Yes and Crucial 480gb should be cool - in my ultrabook i have the samsung 830 with 500gb
If a mouse pad can be noisy, then I think it would be TT branded: seriously, I've lots of doubt about any TT product, however, these are my prejudices.
The proposed 400FL will fit, but given some bad user reports on latest batches, maybe I'd personally rather a Corsair RM or a SuperFlower Leadex/Golden King. A more value oriented choice could be a Cooler Master VS or again a Super Flower Golden Green. The BeQuiet E9 and PP10 are extremely valid choices, if you live in Europe, and so it goes for Enermax Platimax.
Another (pricey) option for a quiet mITX rig is the EVGA Hadron Air: a 500W 80Plus Gold PSU made by Seasonic, fanless up to 50% rated power, and the notoriously gorgeous EVGA chassis. Maybe not so high quality but very stylish.
Among the passive ones which ones is the best bang for the buck?
Offered here in my region (Austria) I have: (C6/C7 supported)
SilverStone Nightjar Series 500W ATX 2.3 (SST-ST50NF) (passiv) 80€
SilverStone Nightjar Series 400W ATX SATA (SST-ST40NF) (passiv) 112€
Sea Sonic Platinum Series Fanless 400W ATX 2.3 (SS-400FL2) (passiv) 117€
Sea Sonic Platinum Series Fanless 460W ATX 2.3 (SS-460FL2) (passiv) 125€
FSP Fortron/Source Aurum Xilenser 400, 400W ATX 2.3 (passiv) (AU-400FL) 126€
FSP Fortron/Source Aurum Xilenser 500, 500W ATX 2.3 (passiv) (AU-500FL) 138€
Sea Sonic Platinum Series Fanless 520W ATX 2.3 (SS-520FL2) (passiv) 138€
About the coolers: for the proposed Fractal, I would look to something like the Noctua NH-U12S, as already seen on this forum (you can use it passive on a dual core, giving a good and close rear fan).
On the EVGA Hadron you have a 140mm height clearance, so I would go for another Noctua, the NH-C14.
At any rate, Noctua and Scythe should be preferred due to their remarkably good stock fans.
What about the Zalman FX100? its only 63€ and could do the job with the pentium or?
Last but not least, the GPU: more probably that not, the MSI Gaming is the best 750Ti on the market.
Nevertheless, noise-wise, I think that it cannot beat any cheaper 750Ti with an aftermarket Arctic Cooling Accelero S1 Plus slapped on, so think also about this.
I will consider this - the MSI is still good value i think (132€). The cheapest available here is the Inno3D for 124€... i dont know..
Look into [Official] Fractal Design Node 304 Owners Club, you will get tons of ideas into what you can build on it.
I found that also... somehow the node is very "stuffed" and i think i have the space as long as it is passive..
So the current part list changed to:
Intel DH87RL 103€ mylemon.com (should be quite power efficient)
Intel Pentium G3430 79,83€ mylemon (as suggested)
Zalman FX100 62€ mylemon (well, its passive)
MSI N750Ti TF 2GD5/OC Twin Frozr Gaming mylemon 134€
Arctic Cooling Accelero S1 Plus 24€ mylemon (as suggested)
Kingston HyperX blu. DIMM XMP Kit 8GB 68€ mylemon (a kit should do)
Crucial M500 480GB amazon 224€ (a lot of space is welcome)
SilverStone Nightjar Series 500W ATX 2.3 mylemon 80e (from the reviews not the best.... but cheap)
