Actually, the PSU does have a 115/230V switch...at least the one I received last week does. It's simply covered by a sticker. It is preset to 115V and then a sticker placed over it, I suppose to keep the evolutionally-challenged from mucking it up...ya know, since those who build computers from the ground up are usually completely unfamiliar with the process [sarcasm].
With regard to the build quality, no, it's nothing to get excited about. As I stated in the beginning, I ordered it to build a secondary system that I can leave alone while it performs computationally intense operations...PCB routing, video compression, etc. So in that capacity it should be sufficient.
Best regards,
