Curtis,
there are some other boards you might also consider.
gvp Gforce 030 - i would go for this over the a2000-030
the IVS Vector takes 32MB ram ,has scsi and uses standard 30 pin simms.
the CSA derringer is up to 030/50 and can take 32MB ram in 72pin simm-no scsi - hard to find accelerator
the Viper520cd is 020/33mhz(if memory serves) has 8MN on board,3.0 roms,ide - scare also.
Viper 530 i think will also work in the 2000.
If you want to go high end there is the blizzard 2060 with 128Mb,scsi,68060 etc.
list here:
