I have an M2284 like that. Of course, you can do it with a 5.25" winchester or even a 3.5" one as well, if it's the type that has a flat top cover (note that some Seagate 3.5" drives have a flat *baseplate* to which all the gubbins are mounted -- it looks like just a cover, but it isn't). Just take off the cover, and use it as a template to cut out and drill a perspex replacement. Or even cover it with clingwrap (saran wrap, I think you colonists call it), but keep people's fingers away from it. -- Pete Peter Turnbull Network Manager University of York
