I'd assume this is more than necessary for most gamers; I think the whole NKRO thing is just overkill. Only Dr. Octopus could make use of NKRO...
The geekhack wiki needs to address the whole NKRO thing and specifically say it's a redundancy factor for the entire board.
In simplest terms USB standard HID = 6 KRO + 4 modifiers. USB non-standard controller(ex: Noppoo choc mini) full-NKRO using multiple keyboard style I/O. PS/2 full NKRO or high volume NKRO.
But most people seem to focus on the port limit i.e. USB/PS/2/USB-mod and or physical limitation as in I don't have enough fingers to hit that many. When instead NKRO should be labelled a redundancy factor i.e. in having the additional 20-30 dollar price tag for NKRO diodes or Topre-style PCB nestled hierarchy. You eliminate ghosting/rollover issues on any combination of keys you choose to use the keyboard for gaming.
In simplest terms despite the fact I don't have a need for so much NKRO volume. If I decide to use a non-standard or uncommon layout for a game I would still like the same equal capacity throughout the entire board. Compared to say the Razer blackwidow and it's "gaming-optimized" layout which results in issues with non-standard users such as arrow/numpad users or ASDF users or IJKL users etc.etc.
Upside down switches
I made a thread on this and
posted on another as well with a similar user mentioning the same thing but some of the posts were deleted with the update. This is actually noticeable difference for me at least when I tested it out.
Even this person thought they felt weird comparing the Das and blackwidow mx blues So they do make a difference in feel and it's primarily because the tactile element even the linear element on the mx black are towards the fingertips i.e. largest concentration of nerves. While normally with the diode socket down the elements are against your fingertips towards your nails. Some might say there might be no difference but I disagree and certainly feel the switch better. Plus I also feel like I'm typing against a backing more so towards the linear switch but it provides a better feeling of the angled but flat stem(feels a bit more stable, supportive as well when pressing down for all three little but again a bit more so towards the linears though).
