No idea but I highly approve of NZXT cases after my last one; which was my first one. I feel their cases are worth the extra. Mine runs way cool just on air cooling alone. Just had to share my love when I saw the topic.
Yeh its a custom job all the parts can be brought separably dont know why they used an older rad on the top though you can get the thinner ones which are just as good, they are also a pain to upgrade if you go with watercooling or when they break down especially if you give away the CPU cooler and throw away the cup mounting support. Also you "should" clear them out every few years this is something i always forget to do, the result equaled in the pump/res combo breaking down 1 week without a computer as not enjoyable lol (had to order a new heatsink and fan can not afford to replace at moment plus im looking to upgrade so kinda pointless)
As for tubing i just got some black uv tubing, though i think see though is best as for fans ive gone though a few some died within a few months (way before they should of) others are still going but then they were expensive one and imported can not remember the make of them though plus they are 7/8years old now.
