a3000d tower and mediator 3000 questions

[KThunder]

hey
i am going to put my 3000d into a nice big pc tower case. later i may want to put a mediator into it. does anyone know how everything should be laid out so that slots line up with stuff and everything.

thanks for your help ive searched online for stuff but didnt really find much. i want the 3000d towered mostly for drive space. ill probably do that and mod it later if i get the mediator.
i want to get a video card and accelerator for it. after weighing the costs of a mediator and voodoo5 pci and sound card i think that just a normal zorro3 vid card will do for now. i do have a ati tvwonder ve card that would be neat to tinker with.
maybe if i see a mediator on ebay (havent seen many)

i have several full size pc cases and am quite good at mods. i have modded a couple of the cases already. windows lights fans etc. the mirage is way too expensive. im sure it is a beautiful case. i have an all black case with window and sliding drive cover that im going to put a decepticon etching on.
i have a PIV system to put together too so i dont know which case ill use for which.
