Optical Drive Does NOT Align in SN25P, Any Ideas?

I just purchased the Shuttle XPC SN25P case and motherboard. However, after I completed assembling it, ... the optical drive does not align with the door on the case. I have a new Sony DVD-R (model DRU-720A), but the problem does not appear to be with this specific drive, as I have tried all other CD-ROM, etc drives I own, and none of them line-up correctly.

Any ideas?

Also, ... and by the way,
This is an Athlon 64 system I am building, is it worth it to install Windows 64 and will it get any more bang for the buck?

Thanks,
Vil

With regards to Windows 64 - depends what you're using it for, as someone told me, check your crucial components and USB devices have driver support for 64 bit.
Also, you should have at least 1gig if not 2gigs of ram to really take advantage.

I am not sure about the drive align problem, I'm not getting mine til Friday!

Well i've taken the bezel off my DVR109 and it fits - is it possible to unclip the bezel on any of your drives?
