I would say be wary of acrylic tubing, it can shatter. I personally would not risk it and I used PETG in my build.

Conversely PETG can deform if it gets too warm (including warm, but not unreasonable water temps). I serviced a build for a neighbour this year where the PETG had deformed just enough to pop out of its fittings.

There's a trade-off there, but for me I'd rather have more challenge building the loop, and less risk in its day-to-day use. Acrylic is tough stuff, I've manhandled a lot of my tubing and it's been OK. There are even some stress fractures in my loop and it doesn't leak or draw air in after years.

The main time I've fractured acrylic was when cutting and shaping the ends during assembly.
 
both acrylic and PETG has its pros and cons. I've used both and had no issues thus far.

In terms of bending, i feel they are both the same in terms of difficulty to be honest.. in fact i'd say acrylic was easier.. perhaps it depends on the type of tubing. I use the Bykski Frosted acrylic and find it easier than other manufacturers. PETG i have used EK and Bitspower tubing and those are easy to bend too. The most difficult one i had and would steer clear are Alphacools tubing.

For PETG to deform, the coolant must be 45c + over a period of time i reckon. One of my rigs which has been mining 24/7 pretty much for the past 4 months is running with PETG tubing.. coolant temp in the early 40s and no sign or any wear thus far

Somewhat frowned upon by hardcore enthusiasts and overclockers, PETG is an awesome choice for beginners due to being way easier to heat up and bend than Acrylic. Aside from that, it has a bit less clarity, it’s more prone to staining and it has a much lower melting point. While that does allow easier bending, it can also be an issue if your coolant gets really warm (above 40°C) due to either summertime + overclocking and not enough radiator space, a block being clogged or a pump failure. Whatever the reason is, the main issue of PETG is the potential to get deformed due to high temperature and pressure. This often happens at the ends, where compression fittings both grip tightly and heat up the tube because of their nature as metals to absorb heat from the liquid. That can lead to bad aesthetics in the form of a bulge or even leaks if it goes to the extreme. This is especially the case in a thin wall (10/12mm) tubing.

To be honest I've never heard of hard tubing in matte black at all (unless it's painted). But a quick search found me this acrylic stuff:

Sounds about right - I know 60°C is considered very risky and this is usually the limit of pumps too. My coolant peaks at 44° as the PC is geared for silence :) That takes several hours of continuous 100% load though.

The deformed PETG tubing I removed from the kid's PC had bulged slightly at the fittings, but had shrunk where the o-rings squeezed it. Just enough to pop out I think.
 
I am not sure how they would have an acrylic tube pc delivered. The thought of acrylic tubing with a full loop in the hands of a random courier is not a comforting thought. My Pc will never be moved so should be perfectly ok with acrylic. I may consider it in the future but the OP has a choice to make in that regard if he orders a prebuilt WC PC from where he is thinking about.

Does remind me that I need to order a water temp sensor and will install it when I rebuild with a new vert mount. Always something to tinker.

I keep reading lots of issues with pipe clouding with PETG and then you're greatly limited to a number of dyes.

not in matt black, but Monsoon and Bitpower do Black tubing.

Black brass looks quite nice and more like a matt finish:

Depending on the company, most would use a pallet, and use that expandable foam bag (can't remember the name of it) but looks like a jiffy bag that when activated will blow up and mould around the components... especially useful for protecting graphics cards etc.
From videos i've seen, the rig will be bled before delivery. It would be the end user to fill the loop. Usually they would be provided a filling bottle and a bottle of liquid for the process.

I wonder if that was what he used but in black nickel.

Looks like black chrome plated tubing.. as seen in Bit-Tech
