Here you have some pictures of the build, sadly i didn't take any before starting:
Added some LED strips:
Overall, i think they nailed a masterpiece with the SF3, I can't think of any competitor for this case for air cooling builds below $200.
Measuring 8.9L with standard ITX components, two top, well vented 12015 fans, 2.5 slots GPU, easy to build in (in comparison with many others sandwich style cases), good side mesh panels, superb build quality and under $100... (sure, you may have to add the riser, but in my case I already had one).
My only grip with the SF3 is that the spine/middle tray seems to be in place by a notch/indent, to me it doesnt feel "secured" or sturdy enough, the motherboard itself has a little wiggle of about 1-2mm if you move it.
Everything else, is top notch. Most of the competition have worse disadvantages than this one while costing the double if not more.
Feel free to ask if you have any specific question.
