Ok so my Antec GX500 ATX Mid Tower Case has front panel USB 3.0 ports,but my ASRock 990FX Extreme3 ATX AM3+/AM3 Motherboard does not have onboard USB 3.0 headers.Will these parts still be compatible or will i need some kind of adapter?If i can get the parts are compatible anyways but not utilising USB 3.0 i dont really mind as i dont really feel the need for usb 3.0.Thanks in advance to anyone who takes the time to answer:)

The case just provides the ports but the motherboard is the part doing the whole thing, so you will actually end up with a PC without USB 3.0 :) 
There are convertors from 2.0 to 3.0 and the opposite but then the 3.0 will act as a 2.0 and be 10x slower, but thats only if you really need those ports and want to use more money :) 
Like you said not all devices support 3.0 so it's up to you if you want a new motherboard, a convertor or just stick with 2.0 only and the 3.0 be unusuable :)

Hi,

No prob, USB 3.0 connectors are downwards compatible with 2.0 You just dont get the speed bump and dont need an adapter.

If you decide you do want to be able to run at 3.0 speeds on those connectors, there are USB3.0 adapter cards that plug into pci-e 1x slots. These range from perhaps US$10-$30 depending on whether it provides internal AND external USB3.0 connections (and how many), whether it provides USB3.0 headers (which is what the GX500 front USB3.0 connector cable uses), and so on. Most cards get their power (for USB3.0 high-power support) from either a 4pin Molex power cable or a 15pin SATA power cable. Some cards provide a connector for both. BE SURE to read the USER reviews for a given card. Some USB interface chipsets (on the card) are better than others at playing with systems and devices, and some cards appear to have port recognition and "wake-up" from sleep-mode issues. Semi-pro "product" reviews usually test a very small sample of cards/systems/devices and may not discover/report such glitches.
