Interesting...
I have yet to tweak or modify this system yet, It has all the programs you would ever use installed.
Im surprised without tweaking I get about the same startup time as the more powerful computers.
Here are the specs for the computer I just ran it on...
Pentium D 3ghz (dual-core)
2GB DDR2-533 RAM
XFX 8500GT NVidia
120GB SATA HDD
Vista Ultimate X86
