I don't endorse this for the usual reasons: not every "influencer" on eBay is what I would call "authoritative", and just because they can build a dedicated rig in something the size of a Kleenex box does NOT mean that YOU can...or even moreso, SHOULD.
When Dieter Doepfer came out with the "beauty cases", he named them that for a reason. They're cute and all, but they don't have enough space to come up with a proper build...even a limited proper build in a lot of situations. What they're best at is to be used for "mission-specific" purposes, especially if you're pulling modules for that "mission" from a much larger system. They're LOUSY at being housing/power for full-on modular builds, though.
Secondly, I think I can run even odds on whether your first low-lighting gig with this build causes you to throw that thing against a club wall. The NE circuitry is good stuff...but the PANELS look like someone hurled up a stomachful of India ink and then poked at it with a dental pick to do the lettering. As of late, they ARE doing more sensible panels...but these earlier ones just look like hammered dogshit. Just try lowering the light in the room to typical venue levels, then try and patch/program that build above. You will go immediately berserk! Ain't kiddin'!
sacguy71 and I agree: get a bigger case for starters. And both of us would definitely suggest the Tiptop Mantis, which is quite portable (Tiptop even sells a dedicated gigbag for it!). And another good reason for this is:
Intellijel Palette 62 = 62 hp 3U, 62 hp 1U, powered (1200mA on the 12s, 500 mA on the 5) = $299
Tiptop Mantis = 208 hp total (2 x 104hp), powered (3000mA +12V, 1100 mA -12V, 300mA 5V) = $335
Also, not only does the Mantis make a lot more sense, Tiptop has a case coupler for the Mantis line...meaning that when it's time, you can slap a second Mantis onto the first one. Put the upper one almost straight-up, and the lower on its angled "feet", and you get excellent ergonomics. With a cab like that, you can keep extending the synth's module complement pretty painlessly. Use the Palette 62, and you're sort of stuck in that regard.
One other point about a bigger case...bigger case is friendlier to bigger modules, and if you intend to play this AND your axe at the same time, bigger is better. You sure as hell don't want to be twiddling tiny controls while playing...you want your major controls (VCF cutoff and resonance especially, as well as your main mixer) to have BIG knobs, stuff you can just reach out and GRAB without worrying if that's the VCF cutoff or something you'd not want to change. Better still, with a bigger cab you could add a CV faderbank for "immediate" controls without worrying about what you'd just grabbed in amongst all of those cables and knobs.
Also...who's to say that you WON'T want to plug the guitar into the synth? Eventually, that curiosity WILL hit you...and if there's no room for a proper input preamp + envelope follower (see the Doepfer A-119...probably the most popular of these), this ain't gonna happen. Again, this is part of the YT influencer problem...they aren't YOU, they don't have any idea of what YOU want to create, they have no idea of where YOU might want to go next, they're just faces on a screen that don't interact and which often have a (stated or, annoyingly, NOT stated) vested interest with the thing they're shoving in the camera. Create YOUR instrument...not copy someone else's...and it will do what YOU want. And for help, there's this joint right here, cuz we're about the farthest thing from "noninteractive" as it gets!
