The IRman can not be placed next to the display without blocking several PCI slots because of the depth of the IRman enclosure. Also, the circuit board of the VFD is wider than the actual display area, so the window cutout would have to be considerably wider.
The instructions that come with the Pioneer 106S drive says that it can play 3.5" discs using a adapter (which is not included). I have never tried it since I don't use 3.5" discs for anything right now. There is a utility that you can download to make the drives run much slower which makes them almost silent. I wish you could still buy 1X DVD drives?
Yes, the VFD's in the new powerbuy will fit this case.
