To be truly stylish, this PC should actually be operated on six screens, which can be switched between three 19“ 1280 x 1024 4:3 IPS monitors and three 21.5” 1920 x 1080 16:9 IPS or VA monitors. One “old school” and one “modern.”
Unfortunately, only a single Full HD monitor is currently connected to the PC due to space constraints. This will certainly change once we move into our own home.
Mouse and keyboard
When it comes to keyboards, there’s really only one choice that fits the bill – a Logitech G19. It has drivers for Windows XP, and this keyboard is simply good and nostalgic. The small screen is a nice addition, and I’ve always been a fan of Logitech keyboards anyway.
When it comes to the mouse, Logitech is the only option for me, specifically a Logitech MX518. Alternatively, I might consider something from Microsoft, but only in an emergency.
Audio
A smaller 2.1 system would be perfectly adequate for a PC. Anything more than that would be excessive for a PC in my opinion. Here too, I can only recommend Logitech, for example a Z625*, which I have been using on my main PC for many years.
