In Linux, you can get a lot of information on hardware and status by examining 
files in the /proc directory. For example, from doing cat /proc/cpuinfo on my 
system:
[adriano at localhost adriano]$ cat /proc/cpuinfo 
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 8
model name      : AMD Athlon(TM) XP 1700+
stepping        : 1
cpu MHz         : 1833.218
cache size      : 256 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca 
cmov pat pse36 mmx fxsr sse syscall mmxext 3dnowext 3dnow
bogomips        : 3629.05

For disk space and free space, you check /proc/diskstats, etc.
No idea about how to do it on Windows, but programs like "Treesize" tell me it 
mustn't be that hard.
Ciao.
