For such a powerful AIO, why limit to 32gb ram in the HP?
If HP Envy 34 shares a common motherboard with Envy 32, then it will have two SO-DIMM slots. 64GB max possible currently.
Envy 32's chassis design is quite messy internally:
As an AIO, looks like the level of iMac chassis before the aluminium unibody. That's more than a decade ago.
Lots of parts are user-replaceable: M.2 NVMe, M.2 WiFi/BT modules, CPU, GPU, 2.5-inch SATA and etc. So that's a huge plus to power users as well as ppl who want to start with a basic config and do incremental upgrades when necessary.
Let's hope the upcoming big iMac won't be a giant iPad on a stand..
