I've had the laptop for less than a month. In the basic version it can handle a good percentage of games - of course with the right settings. The 512GB M.2 drive ensures that the PC boots up in the blink of an eye.
After checking the parameters and looking for details I bought https://www.alza.cz/kingston-fury-so-dimm-16gb-kit-ddr4-3200mhz-cl20-impact-d6632977. htm and https://www.alza.cz/seagate-barracuda-laptop-2tb-d4506214. htm, both work without a problem.
There are two RAM slots in the notebook, in the basic version equipped with one 8GB 3200MHz module. According to the manufacturer it can handle a maximum of 16GB, according to some information on the forums 32-64GB. Notebook oplyva necessary space for placement of 2.5" disk, but this model lacks the appropriate HW. After delivery of the PCB with the L52024-001 marking - and the corresponding booklet - it is possible to operate the supplied m.2 disk and the plotnak/ssd (tested in connection with the above mentioned barracuda, due to the SATA connections to the SSD I do not foresee a problem in this respect).
The 512GB M.2 drive is - again according to the manufacturer's specifications - upgradable to 1TB. Due to the height of the m.2 slots, it is not possible, apparently, to fit double-sided modules.
Due to the connections to the MB, respectively to the PCB with the wi-fi module, it is possible to operate the Solid State Drive (need to buy part no. L52026-001 - https://www.impactcomputers.com/image/cache/data/products/1/1043497-800x800. jpg), I also found a connection for a fingerprint reader, so if someone was able to get the proper HW and somehow took it out of the panel (or masochistically devastated his new PC by punching a proper hole), it can be assumed that it will be possible to use it here.
After upgrading to 16GB of RAM, Intel Iris XE graphics will take, according to system information, 8GB of memory. All in all, it can be a pleasant surprise - especially for integrated graphics. Of the games I've tried as bechmarking - Dying Light, Far Cry Primal (including high resolution textures), Surviving Mars, Endless Space, Alien Isolation, State of Decay (1,2) at max. Skyrim on max without HD textures. JWE 1.2 at high detail with shadow reduction. All in FullHD. It should be able to handle Division and Enchantment already in the base version, but before the upgrade to 16GB RAM it had problems with 4X games and RTS.
Overall great satisfaction with performance and speed. Especially pleasant surprise brought the laptop due to the fact that it was not used for games (with regard to the absence of dedicated graphics). Upgradability and some modularity is a nice bonus.
As for the negatives:
I would welcome some hardening of the display part. Due to the construction it looks quite fragile and according to information from various reviews it suffers from ghosting. The disassembly of the notebook is - after unscrewing the seven screws - about careful unscrewing in order to separate the HW part from the cover segment of the chassis, which drive or later brings breaking out some of the plastic mini-trays. Overall, it is a construction of quite soft plastic, so I would recommend to consider buying some hardshell, or padded case for carrying.
To install Windows, it is necessary to download and add the appropriate disk drivers to the installation (https://www.intel.com/content/www/us/en/download/19512/intel-rapid-storage-technology-driver-installation-software-with-intel-optane-memory-10th-and-11th-gen-platforms. html). More inexperienced users might be put off by this, but it is a very trivial thing.
