I remember buying a handful of Pentium Pro 150s at a hamfest back in 1997. No one wanted those but my Shuttle HOT 613 allowed overclocking them to 180 with ease. Ran Win NT 4.0 on that box dual booting to 95 when I needed to. Of course 9x wasn't SMP aware but the box had 128MB EDO ram which was a crapton back then. Crazy now as we have CPUs with more L3 cache today than a system like that had memory...
