I thought I'd share my sff rig from around 2013. I used it for about a year until I repurposed the parts into other builds. The only tools I had for this were a screw driver, zip ties and scissors so there was no modification involved.
Athlon X4 750K, XFX 7970, 16GB VLP (very low profile) DDR3, 240GB SSD, XFX 550w all inside of a Fractal Design Node 304. I really wanted this Phanteks hsf, but the AMD mounting holes would have the fans sideways. So I used an Enzotech socket adapter that mounted to the AMD motherboard and offered up Intel 115X pegs. It worked well enough for the X4 processor.
It was a fun a build but I moved on from it because Fractal Design's scandinavian design philosophy just didn't resonate with me. The case quality, finish was impeccable. But it was so understated that it felt suffocating. These days that's changing, I absolutely love their new Torrent.
