I really think that putting win95 in a modern machine wouldn't be the best idea in the world. When the win95 kernel was written there was no DDR ram, the bios'es were quite primitive, the northbridges were more primitive, there was no AGP, ISA was a standard, the cpu was real CISC, etc. I'm sure (given that it even installs), it won't be the most stable machine in the universe...
--EDIT-- forgot to mention that Win95/98/Me was largely based on DOS, a 16 bit OS, and todays CPU's are 32/64 bit... that, on it's own doesn't sound good...
