I have installed Debian on various machines, Compaq (of various flavours) and Dell Dimension... something rather.
Never had a problem; actually the quality of its software (i.e. drivers that just work) contributed to Debian becoming the platform of choice for me.
I also find it hard to agree with misconceptions like, 'Debian = hard to install'. I am still a beginner in many respects, but hard to install Debian isn't. I usually go through the defaults and then apt-get install whatever I need.
Regarding your network card, I found that sometimes it will not install the module if I try and configure it manually at the time of installation, but somehow the card has been identified automatically with no need for any further module install. If that's not the case you could also press F3 and select bf24 at when you boot your install disk/cd, this will give a greater choice of modules/drivers.
