xpd:
What do you currently have that you can use on a new build ? Screen ? Keyboard/mouse etc ? Case ?
That sort of thing you can re-use for a self build PC to keep costs down or to give a better upgrade option.
Yep, I have decent monitor, keyboard and mouse, all of which I plan to continue using. The PC is a Lenovo from around 2015, so case, PSU etc pretty old. I did upgrade to a OK Samsung 512 Gb SSD more recently. A 2 Tb HDD is original.
