Hi there - I have recently been trying to upgrade my HP Envy 27p075na. It uses a Bulldozer 4GL board from Pegatron who used to provided for ASUS. It is an H170 board and I would like to replace it with a Z170 if at all possible. Reason is that I have a 6700T and I am trying to change it if possible with a 6700K which would allow higher clocking speed and performance; and also allow me to use DDR4 instead of DDR3 which is what I currently have. Because this is fitted in the back of an All in one I need to try to remain as near as possible to original board form factor. Any ideas from you guys out there?

The all-in-one will significantly limit your overclocking... it’s not even worthwhile.

Then there’s trying to find something remotely close to being able to fit. Doubt that’ll happen.

Boards like these are very much made to fit the chassis they would be housed in by HPs OEMs. extremely slim chance that you'll find another that fits and even if it does, certain ports and other things might not line up as they did with the original board.

Your best bet is to go through the HP AIO catalogue and find a setup/IO layout that closely matches your own then do some research into the boards they use and do some measurements before you purchase based on what info is available.

Abort! This is a terrible idea for so many reasons - here's a few of them off the top of my head:
  • I highly doubt HP ever made a Z-series board to fit your AIO.

  • Even if they did make one, the AIO cooling designed for your T-series chip would have no chance of handling an overclocked K-series chip.

  • If such a unicorn exists and is available to buy, it'll be ludicrously expensive - probably so expensive that you could just buy a whole new PC instead.
