Under 350 euro, there's almost nothing sensible.

Thinkpads
If you want to gamble, I would at least put on a GeForce GTX 1050. Otherwise, it also does an integrated graphics unit. If you just need a bit more power as far as the graphics card is concerned, I would opt for an AMD Ryzen because the integrated graphics unit has a lot more power than Intel's integrated graphics chips. For a multimedia device, an AMD Ryzen 5 is sufficient and otherwise just an Intel Core i5. For an office device, I would put on a Ryzen 3, as it looks from the price-performance ratio often better.
As for memory, I would put at least 8 GB of RAM. 16 GB are useful, for example, for complex image and / or video editing. Partly also for various games with high system requirements. The size of the hard disk can only be determined by you. In any case, I would make sure that an SSD is installed, as this provides for a speed boost again. There are also devices where both an SSD and an HDD is installed. An HDD is just useful if you need a lot of space for other files.
Otherwise just make sure that it is a device with Full HD resolution. And it can also be quiet a device without an operating system, as it often saves a lot of money. An OEM license for Windows 10, for example, you get on MMOGA for little money.
