What..... So I'm working on my design for my new custom case, I'm measureing eveything precisely and when it came to the 5.25" drives, I'm confused, because they aren't actually 5.25" wide.... So then i go to wondering as to what actually gives them th name of 5.25" drive bays....

Also, non-related to my random question, another random question for ya.... Who is it that makes those cube cases. Where it's pretty much 2 ATX cases side by side and makes it alot easier to hid stuff.... My design is going to be sort of like that, but now I want to know who makes them and what the name of the case is.... It's the one that can fit a standard ATX motherboard (12" x 9")
 
sweet, that's the case that I was thinking of. But I figured I could build one to fit my needs better for a quarter of that $350 price tag.... They do look sweet though.
 
I don't understand it either. A 5.25" drive is really 6" and a 3.5" drive is really 4". Is it that the same kind of thing as a 2x4, which is really 1.5" x 3.5"? Over time, the size was increased (or decreased) and they never bothered to change it.

Well I can tell you the reasoning behind wood and that's because when it is originally cut, it actually is 2x4". If you by an untreated fresh cut 2x4 it will actually be 2x4. But normally wood is set to dry out after it is cut and that makes it shrink a little bit. If it is a treated bard, that green crap they inject into the wood makes it shrink even more....

But this theory can't be implied to a metal drive.....
 
I believe it dates back to the good old floppy disk drive days. The big bendable thin disks were 5.25" wide and would have their drive mounted in the large slot and the small hard covered disks were 3.5" wide and would mount them in the small slot. From then on, I guess the designation just stuck.
 
Yep, pawstar's onto it. It's due to the size of the disks that were used in the drives that fitted those bays.

From memory the standard 3.5" (ie floppy drive) and 5.25" device (ie optical drive) is designated as a 'half-height' drive too - also due to the fact that the original drives were twice as high as they are now.

Your useless piece of information for the day :rolleyes:
 
afaik for the wood thing, 2x4's aren't 2x4 because you can yeild more boards out of 1.5x3.5, and 1.5x3.5 was generally just as strong as 2x4...
