Having just finished my own experience with the 605, I wanted to put my 2 pence to the thread.
The slick case struck me a bit like a a shiny thing to a magpie. Didn't quite take the time to measure, or maybe I was aware it would be a push, but went for it anyway, and boy it's tight in there!
It said ATX case, so I fitted an Asus 990fx with a gygabite 680 gtx 4gb, which takes 3 slots.
Cable management is appalling! Ok, I did go for the longest card I could fit in there, but once in it's impossible to wire up the damn thing, the bar is quite annoying to say the least.
The other big issue with that setup are the drives. I can only fit a single 3.5 on the furtherst bay, the rest only support 2.5" drives.
For the noise, I fitted a Corsair hp55 liquid cooler. I actually had to fit the fan on the outside of the case, with the radiator inside. Does stick out, but I can live with that.
Overall I like the case lot, but after a day of fighting with the beast, I have only one advice: aim small. ATX motherboards will fit, but don't expect any sli or crossfire configurations with both hard drive fittings in place.
