Depending on the spec, there is nothing wrong with 5 y/o PC hardware.
The PC I am writing on is using an 8 y/o cpu and HDDs, and still games fast enough for me.
Having said that, from experience, he wont get that gear back in a working condition; when the rozzers finally returned (Most of) my equipment, it was as a pile of parts (except for the laptop which was just broken); in several black bin liners.
What I never got back, and which they stonewalled on until I ran out of money for lawyers, was a pile of SD cards and a number of (genuine) Windows install media, complete with licences.
They returned my car keys with no comment, a year after denying that they had taken them.
