The thought of putting the 7100+G3 card+Radius Lemans GT inside an "more-eye-pleasing-case" made me do a little, rough i admit, concept-test with the parts in hand. The Macintosh IIx case i have, is quite clean all the way, with ROM SIMM, and filled RAM slots. 5.25" HDD but no 3.5" superdrive (easily replaceable from storage parts) - so might NOT be the case to put into this project if it takes more air.

Hacking the CD-ROM into the case is but more demanding but do-able somehow.
