I have an old Intel chassis SC5299 with an Intel S3200SH motherboard. I also have 6 disks controlled by an LSI-9240-8i. There is also an SSD with Windows Server 2012 loaded. Everything was working just fine.

I needed to add a USB controller card. I installed the software, shutdown the server and added the USB controller. I also dressed some cables coming from the LSI to the hard disks.

When I try to power the box on, the chassis and CPU fans spin for a few seconds and stop.

I have never experienced a catastrophic failure before and don't know where to begin to isolate the problem. At rest the NIC light on the front panel is lit. When I hold the power switch in, the power indicator light pulses, the NIC light goes off and the power indicator on the DVD drive blinks. When I release the power switch the fans go off, the power indicator goes off immediately and the NIC light goes back on again.

Any help, please?

Could be the PSU is not powerful enough. Check its label as to wattage total, and for each rail.
If the problem started when you added the extra device, then disconnect it and see if normal operation returns.
But also remove and reseat the main power connector and any other motherboard power connections.
A common failure cause with a computer is the BIOS battery. It is only a backup for when no mains power enters the PSU and provides the stand-by +5 volts, for USB features and BIOS/CMOS needs. And the real-time clock!
If the battery is weak, the real-time clock may stop.. and many motherboard designs are dependent on the clock working to show life signs. Typical battery life is 2 to 3 years, depending on use.
It is normal for fans to spin for a few seconds when powering on, so the BIOS monitors can check that they are working.

I am afraid I have made the situation worse.

First, perhaps I'm paranoid, but when I turned power on, the PSU made a whirring sound and exhausted a little air in the back.

Then I replaced the battery with a new one. When I plugged power back into the PSU, both the CPU and rear chassis fans started rotating without the power switch being pushed in.

There is a command line in the BIOS pages concerning how the system will react if power is lost. For an unattended server or other computer that needs to be constantly in operation, the command can be set for "last state" or "power on". For any other general needs, the command should be "stay off".
It is normal that a PSU may come alive for a few seconds, when powered on. Same with chassis fans or code lights.
After changing the battery, it should be a next task to redo all the BIOS pages to reflect how the system is set up.. and to ensure the date and time are correct.
