Absolute garbage. 1st if you're not going to sli - ATX is a waste of space. All you need is ITX.
mITX has a price premium for being small, while mATX and ATX trade places for being the cheapest bracket, regardless of socket and chipset.
On top of that, there are plenty of people who have uses for more than 1 PCIe: more/faster NICs and video capture devices for example. Those of us old enough to remember and own good EAX3+ games also like keeping an X-Fi around for old times' sake.
Then there are Chinese brands like Jonsbo. They make cases that are way better than this (VR1/2 etc, as an example). Corsair is a rubbish brand that is no longer a sign or reliability of quality.
That's mostly just your opinion. I personally find corsair stuff to be plenty reliable and high-quality enough. Price and performance aren't necessarily the best though, especially when you look at their SSDs.
Their ram is an abominable mix of hynix and some other trash, often masquerading as bdies,
Just like literally everyone else? There's 3 DRAM fabs (Samsung, SK hynix and Micron), and they only produce standard JEDEC-spec RAM. Anything beyond that (DDR4-4000, for example) is entirely just the vendors buying pre-binned dies in bulk, binning em some more, putting em on their custom PCB, putting said modules into a box and shipping it.
their PSUs are re-brands (just get a seasonic, really)
Like pretty much everyone not Seasonic or Superflower? I mean, none of the PSU builders besides Seasonic and Superflower have a consumer line up at all... Also, that trait does NOT apply for the HXi and AXi lineups - those are custom Corsair designs contract built by Flextronics and Channel Well Technology (CWT) respectively.
and their ssds are outdated garbage.
Just a bit slow and a bit old, making em poor value for money. Last I checked they aren't failing all over, or have extraordinarily poor performance (that crown goes to the BX300's sometimes HDD levels of slow...)
Their keyboards and mice are OK, but there are 1000000 models and they all look the same.
They have a particular style that sells well for their customer base, and a number of models based on features. Could use trimming, but it's not like Logitech is much worse
Don't get me started on AIO asetek re-brands of very questionable quality and very high price.
The majority of AIOs on the market are Asetek, and will be for at least the next 2 years (average TTM for a new product is somewhere around the 3 year mark iirc).
Corsair is becoming an EVGA of everything - low to id quality rebrands at boutique prices.
I just.. what? The only thing EVGA rebrands is their PSUs (and arguably reference cards like FE.. cause you know, it's gotta be reference), cause they don't have PSU expertise in-house. Literally everything else is their own R&D, be it simple stuff like cases, all the way to extreme overclocking bits like kingpin GPUs and FTW-K motherboards...
Back on topic: I do like this case, but like most cases, I do wish it supported a 480mm rad :/
