Just adding that I've found baidu threads for these, you can just Google translate the webpage Looks like the K133 will be matx so won't go further into that but the K77v2 will be 9.7L and a quote from SGPC "The small tail is removed, the top with a fan holder supports two 9cm argb fans, the tail supports one 9cm fan, and the bottom supports two 9cm fans or 12cm fans (depending on the size of the motherboard), because it supports 230x205mm motherboards, yes, There is also ATX power supply and SFX dual support" (Note: Google translated).Looks like SGPC are releasing a K77v2 and a new K133 soon No pictures yet but there are listings on their page.

Also very interested because he said that there's vertical support for it? "Handle accessories are sold separately, supporting both horizontal and vertical placement, saving desktop" or is that just talking about placement for the handle :/
