I have a PM 7200/90 and it works great. has 64MB RAM, and it's easy to fix the no-vram buy finding the cheapest video card you can get that is PCI and works in a Mac.

I pulled a video card with 2MB from a PowerMac 9500 and it works faster. The hard drive could also be upgraded. maybe a USB 1.1 card, ethernet, and you are doing great!

CD-ROM could be upgraded with either a DVD-RAM or CD-RW
