A classic Work station / computer that came with 32MB of memory and a 200 mhz pentium pro cpu with 256 cache. I them found some new / old stock memory and maxed it out with 192 MB of memory ( the system has 6 memory bays ) I also upgraded the cpu to a 200 mhz but with 512 cache on the cpu and yes this system can run the 333mhz overdrive if you have one. but I would leave it as is ( and the system will come with the original cpu and ram that cam in it as well. I also installed a USB card in it. the system has a Matrox video card. and a ISA soundcard ( a good one )
