Hello!  I'm using this old design by Raj:

 

15 Drive Budget Box

Mobo: JetWay JMA3-880GTV2-LF

CPU: AMD Sempron 140RAM: Kingston 2GB DDR3 1333PSU: CORSAIR Builder Series CX500 V2 500WCase: AZZA Helios 910SATA Expansion Cards:

    Supermicro AOC-SASLP-MV8 8-Port SAS/SATA Add-on Card    2 Port SATA Serial ATA PCI RAID Controller Card - Silicon ImageCables: 0.5m 30AWG Internal Mini SAS 36pin (SFF-8087) Male w/ Latch to SATA 7pin Female (x4) Forward Breakout Cable x 2

Hot Swap Drive Bays: Norco SS-500 x 3

 

Now my question (note that I'm a newbie so I may get my lingo wrong here.)  The Supermicro board (PCI-E x4) does not look like it fits appropriately into the motherboard's blue PCI 2.0 x 16 slot.  It leaves a lot of unused space in the slot.  Is it supposed to fit in there?  I don't want to fry my board.

That is correct - the PCIe spec allows for x1, x4, x8 and x16 bus widths.  It is designed to allow 'narrow' bus cards to work in 'wider' bus slots - simply leaving the extra connections unused.  Go ahead and install your card!
