No.  It takes 3 full lenght PCI cards and one half length PCI Card.
The layout of the DNE (baby size) board is pretty much looks like
the DNF (full size) motherboard:                   
            +-----------------------+
            + ram_sock   rvm1 rvm2  +
            + ram_sock   cpu1 cpu2  +
            + 3_pci                 +
            + 1_pci/isa             +
            + 2_isa                 +
            +-----------------------+

The top PCI slot is limited by CPU_1 socket for DNE.  A half
length card should fit.  But all other slots fit full length cards.

Please also note that IT IS NOT 4 PCI 3 ISA as quoted before (also
quoted from Supermicro's spec), but its 3 PCI, 2 ISA, and 1 PCI/ISA
shared (from the picture of the spec that I recieved.).

I noticed two visual differences between DNF and DNE boards (besides
smaller):
           1.  only one transister with heat-sink for DNE (2 for DNF)
               this transister is for voltage regulators.  I think
               DNE is using a different VRM than DNF.

           2.  2 fiewer "Q"-logic chips for DNE 
               total of 5 for DNE and 7 for DNF.

I bought the DNF also.  The only problem (if it is a problem) is that
it's difficult to find a case that fits the motherboard; some cases
won't fit even after removing the 3.5" drive bays (because of the
height of the CPU and its heat sink, and the voltage regulators).

I am thinking about getting another DNE board sometime soon.

Agreed.  I check out Aberdeen before but bought my from Megatrend
Technologies  http://www.megacom.com/  because Megatrend Technologies
is a bit cheaper (also knowledgeable, competent, and friendly as Aberdeen).
I have no connection with either one of them but just a happy customer.
