There is no proper replacement for PS/2 yet. Only PS/2 support n-key rollover with mechanical keyboards (although if I am not mistaken there were some USB implementations). It also has no delay when CPU is under load because it doesn't rely on it.

PS/2 wins on three fronts: First, it supports full n-key rollover. Second, PS/2 keyboards aren't polled, but are completely interrupt based. And third, it is impossible for it to be delayed by the USB bus being used by other devices. There are two types of USB transfer modes - the interrupt transfer mode (USB polls keyboard, when key is sensed the USB controller sends the interrupt to the CPU), and the isochronous transfer mode, which reserves a certain amount of bandwidth for the keyboard with a guaranteed latency on the bus. Unfortunately, there are absolutely no keyboards made that use the latter, because special controllers would have to be used, thus making it cost prohibitive.
So if your keyboard supports both PS/2 and USB, and your PC has a PS/2 port, there's no reason not to use it.
As for VGA ports 99% of Z77 boards have it. So who cares? Don't need it, don't use it.
It's not like you are going to see I/O of the board every single day.
For your original question. The best way to go is to buy separate SATA controller, or go to Thunderbolt/eSATA external enclosure router. There are very few boards with 10 sata ports.
