The main problem with the B100/150 is the anemic L2 cache on the CPU, and
the horrible IDE performance. Maybe they're better if you put a SCSI card
in, but I wouldn't bother wasting money on one. 8-)
My remaining SPARC system(s), other than the T1K, are a pair of U10s. Both
are 440Mhz/2M L2. One is all-SCSI (DVD-ROM and HD) with 1G RAM and the
other is all-IDE with 768M. (if anybody's interested in the IDE one, let

I've got a Dell SC420 minitower (P4 Celeron 2.53Ghz, 1G RAM) at home that
does nothing but backups. I'm trying to find someone who will swap me a
small-form-factor system for it (500Mhz or better, with 512M or 1G of RAM);
I want to find a SFF box and make all the disks into externals with a
bunch of SATA-to-USB2 adapters I've got here. Even counting the external
disk power supplies, I'll use less power in the end.
I'm down to only having three systems on 24/7 at home - my desktop iMac,
my wife's Windows box, and my backup server.
