Corsair Obsidian Series 650D Mid-Tower Computer Case

Page 2 »

Obsidian is a naturally occurring volcanic glass and it is produced when the felsic lava from a volcano cools rapidly. So something so hot can be really cool looking, can we say that about the Obsidian 650D from Corsair? You should be able to make that judgement call after this review.

First Look – Packaging and Information

A plain old box is what the 650D case comes in…NOT! Even though it may look that way you do get all kinds of information from the shipping container. I think it might be one of the more informative boxes about computer case I might seen. You do not have to have flashy colors and wild graphics to sell a computer case, sure you first time DIY computer builders get sucked in to the flash and awe, but when you are really serious about your next case you want to know or see all the little details. 

An exploded view of the case is given on the backside of the box with detail about every item shown. I know you can not read the information from the box in the image so I have taken the liberty to post some of it below.
