For me I don't care what its made of, wouldn't care if it was made of silver-plated clay if it did the job, things I look for when I picked mine...
- Is it different
- Does it fit all the parts I want now and in the future
- Does it have space inside
- Does it have good cooling
Granted my case is clad in aircraft grade alu-plastic but I don't care, for me it looks good, cools very well, has loads of room, gives me upgrade options and its different.
I went through loads of cases, up to and over £700 (what ever that is in $) but for me this case fit the bill, I was originally looking at the BMW Thermaltake Level10GT....
....at £733 but you would not have seen my water cooling setup so I ruled it out, I ultimately when for the normal L10GT as my PC is viewable from the side and I didn't want a "PC facing backwards" in the room, the L10GT is hard to work out which way it faces so it fits in and that's what won it for me.
As you can see, a normal PC would just look like a PC facing the wrong way, I needed something different that looked like it was suppose to face out to the side and the L10GT does that really well.
For me I'm paying for something that ticks box's and if they are all ticked I'm happy, if I'm happy ill spent the money, If you have to question if something is worth it on cost, then maybe you should be putting cost at the top of the list first in which case the Lian-Li cases or any other premium case is not what you should be looking at as your paying extra for design, material and a little bit of exclusivity over your hum drum cases.
If you have to look at the menu and justify why the steak cost so much, maybe your in the wrong restaurant,
