motherboard stand-offs and CD-ROM brackets are mounted to the chassis with screws and nuts. no, i don't own a rivet gun. yes, i've thought of buying one. these worked out nicely, and i put a dab of superglue to prevent the screws from getting loose.

fits pretty well - measure twice, cut once? anyone?

the hard drive will just barely squeeze under the CD-ROM. i will have to mount it sideways because otherwise it gets in the way of the PSU.

PSU mostly mounted. mostly...

amazingly, everything fits...

you can see the hard drive almost touching the chassis.
