I have never seen a Dell with proprietary RAM
Looking at the specs I would bet it is PC133 RAM. Any PC133 RAM should work.
Also, they don't use propriety gfx cards either :amazed: An AGP card should fit right in there.
I actually had an old XPS system. It was actually a great computer. I had a 700Mhz PIII that also came with 128mb RAM and the TNT gfx card. I upgraded it to a 5200FX and 384MB RAM without a problem and got 6 years out of that computer
Actually, my brother is still using it and its running great
Overall, typically the only proprietary parts on a Dell is the mobo and the PSU. Everthing else upgrades very easily.
