Yes, it kicked butt but I sold it ~3 years ago. I had Prometheus installed in the second to top slot and the case would close. So, I was using 3 PCI cards and 3 other zorro cards. The top zorro slot was obstructed, but using only 3 pci cards left enough room to use kickflash in it. What a badass system that was, I miss it :-(
What I would recommend is getting a full (preferably AT) tower, the widest one you can find. Make sure it has the power supply mounted up top, not in the middle and make sure it will take a full size PC motherboard (not mini or baby AT). You will need to do heavily modification, making the back look pretty is the hardest part.
