right, Solid state drives are extremely expensive, but they are sooo fast.
I would build:
Amd 5x86 P90 (160mhz 486 processor)
2x voodoo2s in SLI (3dfx sli is different than Nvidia, it up before u call me retarded)
Even though 3dfx IS technically Nvidia nowadays, thats another story...
4x64mb 72-pin dimms
4x 32gb hard drives (for dos.. has a hard time addressing above 32gb)
and i'd put it in my car, and modify it so that i can use the car for old-school Dos gaming=)
Sure you can get a new laptop and do the same thing, but it just doesnt feel the same.......
