I have 3 of them. All 5.1 and 7.1 receivers in the RX-xxx range. One I got online for $25 including shipping. I did have to spend a couple weeks checking every day until I found a good deal. Another I got for $20 at a garage sale, and the third from a thrift store for $15. You've got to keep an eye out for them and to go sites or places where you'll find them. That does have a time cost so it may be easier to just buy one for $50 and be done with it.
The HDMI 7.1 one powers my PC speakers, older one serves as my sub amp. 4 amp channels for to dual 4ohm voice coil drivers!
I've also tried other brands like onkyo, sony, denon etc. Denons tend to be good but overpriced. Onkyos in this price range are unreliable, all mine broke. Sonys are reliable but the amps are weak on the common cheap models you find. Yamaha is the bets cheap brand.
For computer use you may want to try one with analog line input so you can get proper 6 or 8 channel pcm output without having to deal with the inconvenience can comes with HDMI. I'm using HDMI on one but only because I can clone my desktop between my 1080p secondary monitor and the AVR. If I only had my 1440P main monitor it would be a problem. You can't use HDMI audio without sending a video signal so I'd have an extra monitor to the side of my screen that I can't actually see!
These old AVRs are good for PC use as long as they have decent amps, they can be used for surround sound and/or active crossover. You just need analog or hdmi pcm output (or toslink if you only want stereo).
You can use cheap old receivers with PC because every new feature other than Atmos/DTSX is completely irrelevant. Display format support? Doesn't matter, you plug in your monitor separately. Audio codec? Your PC will decode anything, so it's ok to use a pre-Dolby Digital receiver with PC in 2025. Equalization and mixing? Your PC can put modern AVRs to shame.
Don't go buying up more than you need though. I may have 3 but they're all in use.
