We have had this discussion before. The Antec is a better case than the Coolermaster that you prefer --- this coming from numerous professional reviewers. Its made from thicker more expensive metal and has better cooling. I referred you to the review where the Coolermaster case you like (which was about the same price) actually came in last. Its basically still the best and highest professionally reviewed case for $50 or less.
As for the power button it is fine. I can't remember the last time I actually even touched my server's power button. Maybe when I turned it on the first time?
"Quiet black finish"? I have no idea what that means. How is a black color quiet? I could care less what the inside of my server's color is personally.
The black coating is much nicer than the bare metal.
I own both. The reviewers should be questioned then because I disagree with them. If that is the case I would not trust other reviews they have done.
This is my second case... and both Antec's had issues. Issue at the MFG level and many things appear to be designed quickly and simply. There is nothing innovative about this case.
While I agree they use a thicker ply metal and good materials- the result is a heavier... bulkier case that has a rigid square metallic feeling.
While it might be a bit more sturdy - I can not remember the last time I moved my PC let alone throw it from my roof.
I would entirely prefer a lighter- sleeker case. If I need to sacrifice the thickness of the sheet metal ply for that... so be it. And I don't even mind some plastic to replace the metal if needed assuming it won't crack or break.
The black coating really is much nicer. It's no contest compared to bare metal silver. While the thickness of the ply of the metal is thicker on the Antec it lacks reinforcement in key areas.
So in contrast.... the Coolermaster sides and motherboard tray do not flex at all when pushing down to install a memory module. This happens on the Antec. Thicker metal or not.
Your ok to have your opinion but I am sticking to mine on this case. It's merely average IMO. It is perfectly satisfactory and a joy to build inside with tons of room. But it's quality control is suspect and it lacks any significant features or design to separate it from the others.
Not just coolermaster I am talking about. I have built no less than 12 different PC's in the last 12 months. From cheapo $25 cases to my $350 COSMOS II. While I can say there is a certain separation that's obvious from the COSMOS II it's to be expected from a $350 case.
My $120 Thermaltake is pretty nice but far below the COSMOS II and only slightly better than the Antec at $40. But at the sub $50 level most of the Coolermaster, Thermaltake, or Rosewill cases are clearly on par with the Antec 300 at everything that is important to me.
I just don't understand how the thickness of the metal has any bearing on anything. I never move my PC it sits quietly inside a closet. I would exchange some metal ply thickness for some innovative features, a higher level of quality control, or a light weight sleek design any day as they are more important to me.
You can rate it better on metal thickness- but the power button and reset button are lacking. The thick metal sides remove nice- but are flexible and not reinforced. The motherboard tray flexes as much as any case in it's class when pressure it applied. And the bare metal lacks the elegance and finished feel of a coated model. Last and probably most important- the finish on the outside scratches easily... as my nearly new Antec has serious scratches on the outside black finish down to the bare metal. I simply placed on on top of the other... on the floor and build in it taking it apart exactly twice. While I was not very careful about prevention of such... I was not abusive at all. In contrast I had none of these issues with other MFG's. I bet I build inside my Server case 15 times... from LGA 775 all the way to my current LGA1155. I had four different motherboards in that case- with 20 HDD's over 5 years and it looks as good as my 2 month old Antec.
I would be happy to show a video of two side by side to prove my point.
The Antec is perfectly serviceable and acceptable but I can not place it up high on the pedestal that you do. It's merely average. Some good some bad. Had they labeled my wires better, reinforced key areas, and used a better quality power switch I might recommend it more.
Again- This is not my only case. Not my first. Not my last. I feel like my opinion is solid on this matter. I might be a little harsh because I am displeased a tad bit but honestly I consider myself pretty forgiving of most products and that I generally have realistic expectations. It's a good case. But it's on par with others, not clearly above them like you think.
