It's up to you whether you need the DVD drive or not. It does come in handy when installing softwares that still come on a DVD, such as motherboard drivers, and also for burning/watching movies. But since almost everything is available digitally nowadays, it's used less and less. I honestly can't remember the last time I've even used mine. The El Gato should work fine, you'll have plenty of USB and PCIe ports to work with.
