If you gave up in your pursuit of the Billing Riddle, here’s the solution. If you haven’t tried the puzzle yourself, don’t go and spoil it by cheating … Go give it a shot.
Because we’re making a few inventory changes right now, the bonus question isn’t exactly possible at the moment, but I can give you a walkthrough of finding the answer to the first question (which just leaves shopping cart work for the bonus question).
First, set up a table:

I’ll refer to the clues numerically (1-15), though the process will not be sequential.
Clue 10: The first space on the rack is occupied by the Dual Opteron server.
Clue 9: The server using the Ensim Pro X control panel is in the center space.
Clue 2: The Dual Opteron sits next to the server running Cent OS 4.
Pretty straightforward:

Clue 5: The Cent OS 5 operating system is being run on the right of the server running the Windows 2003 Enterprise operating system. AND
Clue 7: The server running the Windows 2003 Enterprise operating system uses Helm 4 as a control panel.
Clue 1: The Red Hat 5 operating system is being run on the Pentium 4 3+GHz server.
Clue 8: The server running the Windows 2003 Standard operating system has two 750GB SATA hard drives.
Clue 6: The server with an 80GB NAS backup add-on sits next to the server with two 750GB SATA hard drives.
The server running Win 2k3E has to be one of the servers without an O/S and without a CP (1, 4, or 5), but it has to be to the left of a server without an O/S (which means Win2k3E is in server 4, Cent OS 5 is in server 5).
The Red Hat 5 server has to be server 3 because it’s the only server without an O/S and without a Proc, and the Windows 2k3 Std. server has to be in server 1 (because it’s the only remaining unassigned O/S).

Clue 14: The server using cPanel as a control panel has two 500GB SATA hard drives. AND
Clue 4: The Single Woodcrest server has no control panel. AND
Clue 15: The server with two 300GB 10K RPM SCSI hard drives sits next to the server using Plesk 8.2 as a control panel.
The server using cPanel has to have an open space for HD as well (server 2 or 5). The Single Woodcrest has to have an open space for CP (also server 2 or 5). The last control panel space would be in server 1, so that must be the Plesk 8.2 CP. Because Plesk 8.2 is being run next to the server with two 300GB 10K SCSI drives, the cPanel/2×500GB SATA combination cannot be in server 2, so it is in server 5.

Clue 11: The Dual Xeon 2.8 server has two 146GB 10K RPM SCSI hard drives.
Clue 3: The Conroe 3060 server has a Checkpoint X16 Firewall as its add-on.
Clue 12: The server with a LanTronix Spider KVM as its add-on has two 250GB SATA hard drives.
Clue 13: The server with two 300GB 10K SCSI hard drives sits next to the server with the F-Secure Anti-Virus add-on.
The Dual Xeon 2.8 server has to go in server 4 because it is the only server without an assigned proc and HD, so the last proc, the Conroe 3060 must be in server 5.
The KVM must be in server 3 to have the correct HD configuration, so the final add-on must be in server 1.

So the 20GB DiskSync must be in server 4.
Plugging that info into the shopping cart gives the answer to the question: $434
That was fun, wasn’t it?
