If you have a big ram like 8gb ram with ssd let's say like 120gb, you can run a Bitcoin node easy without any delay, all you have to do is to download Bitcoin core like he instructed, install set your prune parameters and then let it sync for you.
Even 8GB is not that much atleast 16 GB will give more space for core to stress the system and if someone wants to download full node then it must be around 650GB so make sure you have atleast 700GB for running your full node and NVMe is recommended since R/W will be faster and it's more reliable.
If I am not wrong, we can even do that using GUI without editing the 'bitcoin.conf'.
