i have... but i used a sis6326 with 8mb.... just make sure you have enough room when choosing the pci video card... besides that the MSI Slim PC is very stable and a lot of people buy them because they can take it on planes and watch DVDs away from home and takes up very little space. these systems come with two Firewire ports, two USB ports, TV out with either S-video or RCA. i think they are rather cool in design because they can go to a 1000mhz PIII.
