Is it worth taking someone's old PSU and case?

[mutazoid]

Someone offered me an old PSU and full sized case.  I think the computer inside was a core 2 duo to give you an idea of the era of PC.

Ive never built a computer and its be ages since I upgraded a system.  Are the cables from an old PSU still compatible with current systems?  What about the case Im pretty sure full ATX has been around forever are current motherboards compatible? etc thank for any discussion....

The PSU will be "compatible", but if it's a PSU from the C2D era, I would change it.

 

The case will be fine, but at that time, space behind the motherboard tray for cable management was mostly unheard of.

Yeah it would all work with modern, non OEM hardware. However given the age

It's not practical to use with any hardware you plan on using long term.

Is it an ATX case and power supply? Lots of prebuilt systems don't use the ATX form factor. Some cases might be compatible with BTX motherboards, or only MicroATX motherboards.
Likewise the PSU may be TFX or some other form factor. Might also use proprietary connectors and not be compatible with ATX motherboards.

Assuming it's an ATX case, then a case is a case. Probably won't look flashy compared to new cases with tempered glass and RGB, but if you just need something to put your parts in it will probably be fine as long as everything fits and airflow isn't restricted too much.
The old PSU is probably not worth keeping though. Don't trust modern parts to a 15 year old PSU.
