great headline. Makes me want to call the fire department to free you.
still searching for a pic of the source 530. You sure that's what it's called? The nzxt switch strikes me as pushing into the territory of tacky if not handled very carefully. When I look at it all I can think of is white pianos. that thing could go Liberace very easily. so this just leaves the 750d.
I google searched black and white computer case to see what else was out there, whic did make the switch look relatively normal. Wow but there is some seriously hideous stuff for sale out there.
The best looking black and white cases I saw over all were both small. Bitfenix prodigy, and a diypc mini q1-b back, which is only $24. They may be too small for you though.
The best looking one I could find that was a full tower was the asus ta-853, which is discontinued, and the LD PC-V8 Reverse ATX/HPTX which is stupidly expensive.
The second one though is interesting, in that it is just a black high airflow case with the inside painted white. if you're willing to put in a few hours with some masking tape and a spray can you ought to be able to imitate the effect on the cheap. This also goes for the Asus. Take a piece of plexi, cut it the size of the case, and sand the back face of it. It will go white. If you want to be clever, get a disc sander and put some interesting swirls into it. Then mount it on the front of whatever black case you like.
