CPU speed-wise, and memory expansion-wise, they should be identical.
Both can have up to 2GB of memory using (expensive) 512MB DIMMs. All
components run at the same speeds and have same capacities, IIRC; ie
both have 2MB cache, same ACER I/O chipset, same PCI bus speed
(33MHz), etc etc.

Both consoles, I believe, will recognize Symbios 1010 and Adaptec x9160
controllers, so SCSI Ultra3/160 support is (natively) possible.

ACER chipset IDE support for DMA is topped out long before SCSI; I've
had no luck getting to 20MB/sec via "hdparm -t" with an IDE HDD that
should have been ATA66, I believe.

Generic expansion certainly would favor the DS10; room for 4 HDDs
(vs 1 on the 10L), 4 64-bit PCI slots (vs 1 on the 10L).

But WRT fan noise; I'd NEVER want a 10L in an office, let alone two...

Well, that would be a very good deal, if expansion/noise is low priority.

Good luck.
