I had a very good experience so far!
Details and suggestions:
- Laptop case aesthetically nice and polished, and seems very well crafted so far
- Linux compatibility is good, just some missing keyboard special keys and lack of control on keyboard backlight
- Production of my laptop was slowed down by theft of monitors stock. That required 2 more weeks for refilling it, but PC specialist promptly notified me and keep me updated nearly daily. This was really reassuring and helped to relieve the stress :-)
- The configurator can maybe more helpful guiding your choice (you need to search by your self each component and try to figure out why something cost more, if is what you need, etc). Furthermore, each item in the drop down should report how it will affect the price (e.g. " 0€", " 200€", etc). This will make selecting within large set of similar things (i.e. rams and hard disks) easier
The most important missing feature for me that I would like to see added in the future is official Linux support.
In order to not be an expensive investment you could just start to keep a db of which components have compatibility issues with Linux, maybe asking feedback from the forum community. Then when proceeding on the checkout if you choose Linux system (Pop!_OS could be a valid candidate) you get notified if there are components with a yellow or red compatibility status, sending people to the component corresponding forum thread if any.
From there you could improve incrementally making by letting the UX displays this info before proceeding with checkout.
Note 1: I will have found PC Specialist way sooner if you would have SEO-advertised yourself as Linux compatible, instead of finding you on a remote forum just this year. You could easily become the first choice in Europe for people looking for a Linux PC, if you advertise yourself accordingly on specialized blogs, etc.
Note 2: Putting Linux in your configurator could actually lowering by 70€ your minimal price (but remember to put OS choice as the first one of the configurator and giving user a warning when proceeding asking if they are actually secure of proceeding without windows)
Note 3: 2020 was really a pivoting point for Linux adoption, now that gaming is much easier (https://www.pcgamer.com/uk/its-surprisingly-easy-to-switch-a-gaming-pc-to-linux-today/), exploiting this trend could get you a very relevant market share in a growing niche
