I run 2 x good, modern PC's of my own (I also have a work laptop but that's issued by my company so I wouldn't count that) plus a few old ones knocking around and a Steam Deck which is a handheld PC of course.
I also have 2 x desks in my office, one has my main desktop listed below on and the other is for my work laptop and that's connected to monitors and peripherals I own (I do not own the work laptop, my employer does)
My main desktop and primary gaming and general use system in my office on my desk is;
Ryzen 9 5900X with an RTX 3070
My secondary PC in the living room connected to my 4K OLED TV which I use mostly for living room gaming but I do also use it for Youtube, Plex and some other media consumption stuff;
Ryzen 7 5800X and an RX 6700XT (this is also SFF, so it's mini ITX in an NR200)
The reason my secondary PC is as new and pretty much as good as my main one is two fold, I love playing games on the OLED so I wanted to be able to take proper advantage of that without buying one to put on my desk aswell and secondly the last couple of years with the various issues we have seen with supply chains and what not made me realise just how important it is to me to always have a 'good' system to use should I suffer a failure and I may not be able to replace a part within 24 hours so easily as we have taken for granted the last 15 years or so, hence I have a really good second system aswell so aslong as I have electricity (perhaps also not to be taken for granted anymore
) I wont be prevented from gaming or whatever I want to do with a PC.
I also have an old I5 2400 Sandy Bridge system which 'mostly' does nothing but I do use it as my CD ripping station from time to time, as being a bit of an audiophile I've never stopped buying CD's, that's how the majority of my music is held and I rip those to FLAC and MP3 myself for use in the car and such and quite often I do actually just run a FLAC feed from the living PC into a DAC which is part of my hifi to listen rather than actually spinning the disks so much anymore, but I do like to have them none the less.
I also have Steam Deck now ....not really sure what for yet, it's a nice piece of kit though
I do have enough parts to throw together some other old junkers should I wish to, got a Raspberry Pi I used to use for Pi Hole too but I eventually stopped doing that as it proved slower than just using public DNS in the end.
I've been in the hobby and collecting parts since the late '90s so while in more recent years I have made an effort to sell on stuff while it's still worth something once I have upgraded or switched something out I have none the less still amassed quite a collection of stuff over the years.
