The spare tower unit I dusted off and stuck in the corner for Monero blockchain shit is working out pretty well, even though its really old.
However, the fan on the power supply is misaligned or something and makes an annoying grinding sound on-and-off (recently more on than off). It doesn't seem to impair function, but its pissing me off. And yet I feel like buying a whole new power supply just for this is a waste of money...
