I'm getting an NZXT Phantom which will come with a ton of bays but I have nothing to fill them with other than disc drives or mem card readers..
Well, there are a ton of cool devices out there. Some of the coolest ones are digital panels that can give info on your system.
One word of warning, the full tower Phantom does not give any external 3 1/2 inch bays. I am a little pissed because I already ordered a bay device. I'll have to use it for another build now. Plus the added expense of buying a 5 1/4 inch card reader.
