Hi. Fellow swede here.
Conrad has a pretty good selection of power supplies. I ordered my last PSU from Elfa, but only because the model I wanted wasn't in stock at Conrad.
As for stepper motors, I recommend OMC StepperOnline. They can ship most steppers from Germany, so you get pretty fast shipping and avoid customs fees.

Sounds good then!
A "LRS-150-24" is ordered it should be quiet since its fanless!
I hope I have enough power with that, it delivers 6.5A and I'm counting that the motors will use something like 1.2A each wich leaves 1.7A to the hotend and electronics.

Anyway, from what I gather both the wiki and the specifications of the motor I'm looking at says I need to count with 2 times the rated current times 0.85 for what is to be used as a maximum.

No, you don't need that much power supply current. Read the wiki page that I linked to in my post.

Have you considered a remote direct drive such as Zesty Nimble? I can highly recommend it.

You don't need to allow for both windings because when one winding is getting full current, the other winding gets no current. The current drawn from the PSU is much less than the current in the motor windings, because the stepper driver is in effect a buck converter.
I believe both Flex3drive and Nimble have already be used with the Smart Effector.

I'm curious on how you are mounting all of your aluminium extrusions,

That stepper is unfortunately a high voltage/high inductance one, so I don't advise using it. I use [www.omc-stepperonline.com] for a 3:1 geared extruder. For the 30:1 of the Nimble, it may be that [www.omc-stepperonline.com] is more suitable. Try plugging both sets of numbers into the calculator at [reprapfirmware.org] and see which one gives you the better speeds.
For the towers, with Duet WiFi/Ethernet electronics my choice would be the 17HM19-2004S that you linked to earlier.

A hexagonal build plate might be even better and would be easier to cut. I'll email Aluminium Warehouse and see if they can do one.
My own printer uses a 5mm aluminium disc from Lakeland Steel. I was lucky, it is flat.

I'm not convinced that adding a hexagonal plate on top of the frame would gain anything, assuming you use metal frame vertices as I do. But I'm not a mechanical engineer, so I could be wrong.
I've emailed Aluminium Warehouse, With luck they will respond on Tuesday.

How did the search for Aluminium go?
Past few weeks I have been dealing with a similar situation here in Norway, no metal company's willing to sell to private-persons, I have a few leads but still am afraid that my search will come up empty handed
I came over this rather sexy adapter for using ATX PSU here, it would not necessarily require an adapter to use an ATX power supply but I like it simple and clean, now its quite expensive but i'm sure its possible to find a cheap replica from China. Not to mention ATX power supply's bellow 600watts are cheap A.F. and readily available.
