OK, well as I stated earlier, I retired my Elite 335, after a couple of months of use, in favor of the CM Storm "Scout".
The Elite 335 is a decent, serviceable case, with understated good looks. This case is the best looking of CM's mostly plastic low end offerings.
With that said, it's also tinny. The Antec 300 is much better made than this case.
Also, I carted mine out of Microcenter for 35 bucks. So, it really isn't a value @ the 50 dollar mark, and certainly not without free shipping.
There is a certain psychological component to the choice of a case. Obviously, taste differs from person to person. But, with that said, an individual looking to build his own machine, shouldn't perceive a case a "a box to put the stuff in", but rather as a design object that states pride in achievement, in having constructed the machine in the first place.
Personally, I enjoy the clear side panels and lit fans of an "enthusiast" case offering. (And I'm an old fart, if you're wondering).
I normally shy away from raising the budget on a build, or advocating a great deal of overspending, but treating yourself to a step up case, (IMO), would add to the enjoyment of your project.
The additional cooling available is a gaming type case may not be necessary for your usage profile, but cooler the better is the best approach. Cases such as the Antec 900 turn already cool running machines, into cold ones.
