I have seen some textual system information on a winxp desktop, no wallpaper, blue background color, white characters. I couldn't find that software that did it, I still dunno what was that.
Still I started to search for skinnable system information apps, and first I found sysmetrix, which is also brilliant, but since I'm into textual infos, I prefer the transparency of rainmeter to the mailchecker, winamp controls, all bells and whistles above a bitmap in sysmetrix.
This skin goes well with any blueish wallpaper, or I guess with anything not too bright.
There are some things to tune to your system in the ini, but you don't need to be a rocket-scientist to perform.
The needed modifications are in the readme, but anyway, here they are:
1.)In [MeasureIP], [MeasureGateway], [MeasureDNS]
you might have to set SysInfoData to 0, or 1 or 2 according to your HW config.
you need to set NetInSpeed=512000 to your nominal max. bandwith. Given in bps.
total memory is not measured, but set in the ini to a fix value, set it to your memory.
total disk size is set to a fix value, set it to your disk size.
