Possible to install KDE on Talos II Power9 systems (ppc64el)

Just evaluating the usage of a Power based PC for AI related work.
Raptor Talos II seems to be currently the only available option, apart a costly IBM server.
Pre-configured come with $3999,just purchasing the mobo, cpu and CPU cooler and other parts in the market come down to about $3000 for a 4 core 16 thread CPU, 64GB ECC ram, RTX 2070 Super GPU and 500GB NVMe SSD.

Its possible to install a working Ubuntu 18.04 LTS, but didn't find any reference for installing KDE DE or Kubuntu flavor.
Will be possible, in your opinion?

I don't know the specific answer to your question, but if I were going to spend $3K on a box, I'd ask the vendor that question...be worthwhile to know how they answer it.

Well Raptor say their systems are intended to be used with Linux, so that's a start. The PPC version of Ubuntu is a community issue, not an official Canonical release, so it might be better to get Debian or CentOS. Both are biased towards Gnome, but KDE is well maintained. But the obvious solution is to contact support@raptorcs.com and ask what they recommend.

@scasey already asked, no answer so far.
@DavidMcCann the goal is use PowerAI sw stack, that support only RHEL 7.6 and Ubuntu 18.04+. Bering the first dropping KDE (in the future) and the second unofficial port with no evidence KDE is working on PPC arch I suppose I'm out of luck.

Considering all for starting I think the best way is to use Nimbix PowerAI cloud offer, for about €1.7/hour you got 32 thread on Power8, 128GB RAM, 1 Nvidia P100 (about equivalent to RTX 2070), needing 77 days of 24/7 compute to pay a Talos II equivalent cost, not considering OS licenses (i.e. RHEL) and time invested for configuration.

Will see how is working for my needs.

My CentOS 7.6 installation had a KDE option, which I wasn't happy with, so I've installed Cinnamon. I suspect you can use any desktop environment you want...CentOS is RHEL for free.

Although I am a bit confused. Why would you need a DE on a cloud server?

Nimbix it's an alternative to Talos II workstation, and it's used trough a web interface.
My question for KDE DE was related only at Talos II usage as personal workstation.
This is PowerAI Vision required software, being not RHEL user nor a Linux expert (using it for ML testing, just pushing to shift on it also my 3D activity) I can't say if CentOS will be also compatible.
