It is definitely worth it. SSDs are perfect for acting as the boot drives. Also, it is easy. In your case, a lot easier because you're using a desktop. According to your case's drive bays, you should consider buying a 2.5-inch to 3.5-inch mounting adapter if your case supports only 3.5-inch drives because all (at least 99%) SSDs are of the 2.5-inch form factor (provided you don't go for mSATA or M.2). Keep in mind that your motherboard must have a spare SATA data port & your PSU should have a spare SATA power cable.
