for all those with the G5 case fetishes.. before you decide to slaughter a PowerMac case and realize that it will look like a right mess with the IO ports, and dremmel heaven.. take a quick peak at this..

it's the lian-li v1000.. and yes a little pricier, but you can just drop an ATX standad board in it with minimum probs ;-) i would have liked it more with just one 5.25 slot for DVD-R
i am also looking for the ultimate case, and this is one that I'd buy if I didn't already have another old skool lian-li case that I like. until there is a an IO panel ATX kit for the G5 case, this is the path i'd take.
i also agree with bofors.. those fishtank pc's make me sick.. my girlfriend has made me open all our electrical appliances and break / disconnect all the leds in the house ;-) and guess what the things still work perfectly without little annoying lights!
here's an excellent review of the case aswell:
http://www.dansdata.com/pcv1000.htmI just got word that there is an updated version to this case.. it's the v1200, and has an updated cooling handling.. apparently.. it weighs a little more and is even pricier, but might be worth it (?) anyone with experience please tell us. ;-)
my nerd wet dream would be to have this in white

but they are only avail in silver / black..
cheers

This is also one of my favorite cases and will be my next case. My friend has a Lian Li very similar (can't remember the model number and too lazy to google it) but is vertical like a stereo component and it is pretty nice. I just wish the floppy drive bezel wasn't plastic.
