Well, more RAM could make a huge difference in performance if your workloads are IO intensive, eg. regularly transferring huge files between VMs (more memory available for caching data that would otherwise have to be re-read from disk; RAM is still faster than SSDs). Regarding the Intel Active Management Technology vulnerability  (CVE-2017-5689), my understanding is that it cannot be exploited over wireless connections (unless the OS is explicitly cooperating with the Management Engine by forwarding all incoming traffic via the PCI communication controller), only wired LAN can be exploited without the OS knowing. If you're still worried about this type of attack, an USB qube used with external USB WiFi/Ethernet adapters might be the best option (although a bit bulky). According to the Xen project wiki , disabling hyper-threading should make no difference as the scheduler used by Qubes is HT-aware (ie. if your system runs noticeably faster with HT disabled, it's definitely a bug and should be reported to the Xen project).
