I think your build looks solid, all around good components.

Unlike many other high-end coolers, the Noctua is widely available in Denmark, and I like the top-down layout. I seem to remember that this cooler may overhang the edge of the motherboard, so I'd be interested in your experience using this heatsink/case(/motherboard) combination. I'm considering a swap for 500 RPM Slip Stream 140s, and since I also intend to use a pair as case fans it makes sense to order them all at once.
I think its a great cooler, but i would also consider Scythe Mugen 3
(not sure if its available in Denmark), but in my experience with the new Sandy Bridge boards (with intels) they come with 4pin PWM fans connectors, so ideally i would go with PWM fan and you can tweak it via BIOS. I bought an Scythe Kama Flex PWM
for a recent build, like the Slipstream PWM fan, is a 300rpm to 1600rpm, the intel mobo at stock has it running at 291rpm (you still have the option to crack it up if you need it), to me its inaudible, so for this reason i would go with mugen as it comes with similar PWM fan, and probably better acoustically than my SFLEX.
Another great cooler with a fan is Thermalright HR-02
+ Thermalright TR TY-140
, the fan is also PWM, the intel mobo has it runing at 701rpm stock, also very quiet fan, i would assume the slipstream is more quiet specially since it dips down to 300rpm, this is also a very tall heatsink.
According to Fractal Define website for the Mini
"Supports CPU coolers with height of ca 165mm", so the Mugen3 (158mm) or HR02 (162mm) should fit, kinda tight but if specs are true it should.
I like your choices of case fans, im also planning a build for a home server with Define R3 and going to change the frontal fans to a 500rpm slipstreams and still thinking on using 800rpm on the back with the mugen 3 cooler for the cpu, for your build i would start with only 2 (1xfront 1xback) or 3 (2xfront 1xback) 120mm slipstreams 500rpm and see from there if you need more cooling you can add more fans, the less fans you have the less noisy it will be.
