First system bring back fond memories. Patience is the key word here that and have someone like VDr to ask questions of.

As cases go Antec are the more popular choice of my clientelle. The SX1000II has the features you are looking for and more. Such as modded side panels LED fans and light tubes. Fully tricked out these cases look really cool. They're large enough to accomodate just about any future upgrade you want to consider. Even if you're not interested in the case I strongly you think about going with an oversized case. Easier to upgrade\work inside of, better air flow hence a cooler working temp.
