Okay, I have the machine. It's arrived safely (thank God), it's been cleaned up, and it's hooked up and tested. 😀 There are a few things that need sorting. The biggest issue is the noise 🤣. It's crazy how loud the computer is and then you go back to your main one, which is whisper quiet. I'm not quite sure what's causing the noise in my retro PC, whether it's the CPU fan or the PSU. If it's the latter, it may need replacing with something quieter. Having it next to me to my left, it's almost deafening 🤣. It's like an airport runway. Have yet to open it up and investigate.

I've also noticed under dxdiag, that it's saying it's a Pentium II despite the sticker on the case, and at startup, saying Pentium III. The speakers are built into the monitor so it looks like I need to see if I have a spare audio cable. At any rate, I'll need to look at getting some vintage speakers at some point. And finally it'll need reformatting to get the rid of all the crap on it. I've been given the original Windows 98 disc, which is great, however I don't have any license key. I presume that was very much a thing with the first release of Windows 98? I can't recall if our old copy of Windows 95 has one, but our 98 SE certainly does. Worst case scenario, I'll just install SE, which is probably a good idea anyway.
