BitFenix Portal Mini ITX Chassis Review - Product Gallery

When we flip the chassis on its side we see that the bottom has proper rubber grips covering the stands which keep the case from sliding around and of course help to prevent resonating noises and thus dampen noise levels. The PSU fan area has extra ventilation holes applied, this also functions as a huge air intake for the PC innards. 
 

Now, see the photo above with everything in place but no removable side panels eh? There's something I want to show you:
  

At the rear side just remove the two lower thumbscrews, once done... you can pull ou the entire motherboard tray twards the back. Evrything is seated on there including SSD/HDD bays.

Once you have pulled that tray towards you. You simply can lift it out of there. See the metal bar to the lower right ? That moves in and out of the PC and here is what your motherboard tray is mounted on. The mount itself feels incredibly sturdy and everything fits precisely without any clearance issues. It is very nicely designed.

So here we open up the chassis and get a better idea of what it is all about. Inwards you can see the spacing some cabling etc. For an incredibly compact design there simply is space enough as you can mount all components outside the chassis thanks to that removable tray.
