hehe actually they sell those cases of the plane and stuff retail- go check out xoxide.com - they're not fabricated nor are they the work of some serious modder ^_^
the case you picked is in the 100 dollar range; i think for the pice, you could go other directions in terms of quality- if you want to just mod a case, you can get a cheap one and do your own mods but certainly not for a 100 bucks..
for the price:
if i didnt have a nice PSU, i'd get a nice antec because they make high quality aluminum cases (heat dissipation is better) that come with high quality power supplies
if i did have a nice psu, i'd get a Lian Li, Cooler Master, and heck, i'd still get a nice antec... they have nicer cases with removable mobo trays, they pay attention to details, and some even have noise silencing features... the Lian LI- has sound insulating foam and other great features to boot.... i would not want a poory made plastic case--
