I really liked the Antec 1080 series. They are heavy and well built, except for the front door. Really easy to break off (which is true for most Antec cases). Lots of room inside, which is good if you plan on water cooling or stuffing it full of drives.
I've since switched over to the Antec SLK3xxx series. These are a few inches shorter than the 1080s (which reduces the amount of interior space), but, make up for things in the use of 120mm fans. The SLK3xxx series pretty much holds the same number of drives as the 1080s. You can make a fairly quiet computer with these cases. Another nice thing is that you don't need a really long data cable to hook up 5" drives at the very top of the case, like you would with the 1080s.
The Antec True430W is a good power supply to start with, but, personally I would buy something bigger (i.e., at least a Neo Power 480W). You won't come close to filling up a 1080's drive bays before that 4320W PSU is over taxed.
