Well, another thing that you might consider is that, every time that I have seen it, and IMHO, Evercase = "off brand"
Not that there is anything wrong with that...
But the current case that I am/was using was branded as an "Evercase" by the website that I bought it from. It was, well.. a case. Nothing to get too excited about. Cheap feeling, thin metal exterior that's really floppy and just not very sturdy feeling. The paint is rough and course, and, just as the metal, of very thin material. Nothing too special about it, you got your drive bays, motherboard mounts, PSU hole, etc... Everything feels rough and you could probably slice your hand open at any moment on the metal. Like I said, "just a case...".
However, I'm doing a major upgrade (well, basically a new computer but reusing drives and video card, I guess ...

). I ordered an Antec SLK3700AMB last week and received it yesterday.
Well, after I did a few mods to my Abit NF7-S board and installed the CPU and HSF, it was time to put it in my new case... So I got out my knife and proceeded to open the fancy box that my Antec case came in.
After I opened the box and removed the case, I immediately noticed something significant about it - this is a QUALITY item, in a MUCH different class than the "off brand" computer cases that I'm used to! The paint was very shiny and smooth, and the actual metal and body of the case was THICK and STURDY! Being my first experience with a "name brand" case, I'd never seen anything like it!
Anyhow, after getting it out and taking it apart, you notice that the attention to detail (and quality in that detail) is very phenominal. I'm in love with this case!
Heck, even the screws are smooth, shiny, heavy steel! (as opposed to the lightweight steel alloy screws that have come with every other case I've used - and I used to build PCs for family, friends, friends of family, friends of friends of family, etc. etc... once one person learns they don't stop calling!

)
... Basically what I'm trying to say is, I recommend NOT buying an "off brand" case just to save $20 or so.. trust me, the difference is WORTH IT!
If you've ever worked with other cases and then try out a name one (like Antec), then you will definitely notice a difference almost immediately!
That's just my $0.02, take it as you will...
