I have a 13 year old tower PC system with a Intel Core 2 Q6600 CPU and 4GB of RAM. This was pretty much high-end back then. It still does what it should and I use it as a Linux-based server for my personal applications which tend to be quite CPU-heavy using all cores. Graphics don't matter.
However, this thing is just heavy and loud especially since it runs 24/7. Also, I can't really use a modern SSD with it as it has only SATA2.
So I wish to replace the PC with a slim modern equivalent. With all those miniPCs and alike computers on the market I thought I could put a nice small one of those on my desk and still have the same or better performance.
I have looked into the HP ProDesk 405 G4 6QS11EA. It has 16GB of RAM, a quadcore Ryzen 5 CPU and a 512GB SSD. This seems just perfect for my own personal calculation-heavy server use.
However, this little guy is marketed for office use so I am unsure if am missing anything.
Would you have other ideas? By budget is up to 600/700€ or $.
