jonnyp, yeah I'd like to a build in the same case but a contemporary high spec gaming rig. For this case I think you'd have to do mini itx, mainly because of the curved design, but there were big cases back then that would give you more room.
Regy, sounds like a handy stash for someone like myself..
It turns out that ribbon cable that connects the soundcard/ drive bay is a Creative proprietary ('AUD_EXT') type of cable.. Great. I have seen a round one of these, but its gona be real hard to find one since they are discontinued and only shipped with the systems themselves.. I can only even find one of the ribbon type that I have and thats in the US on ebay.com:
Inside of the case is gona remain messy for a while I think..
