At the moment we have no interest sorry because the value just doesn't add up. You can't pack much into an AIO because most people want them as slim as LCDs, and generally speaking everything 'gaming AIO' on the market is a poor compromise compared to buying an LCD and a separate desktop, plus, generally you can upgrade DTs or replace them without having to replace the display for less money.
HP make some upgradable workstation AIOs with full size GPUs in them but they are loud, chunky and cost a fat $$$.
The closest thing we have is to VESA mount a GR8 on the back of your monitor.
