how many usb ports is "a lot"... many mobos have some ports on them, and many cases have 2 or 3 on them too... i have ony my motherboard 4 or 5, then on my case 2. thats at least 6 usb ports..cant imagine your gonna need more then 2, 3 at tops... but deffinitly not 6.
USB ports is a minimal requirement when buying normally, but 6 isn't really "a lot". I use 6 typically, 7 at most.
As for what to look for, there are certain brands to stick to, from there it's mostly a comparability game.
Some of the best are:
Motherboards: ASUS, Gigabyte, EVGA
GPU: EVGA, ASUS, MSI, Sapphire
RAM: OCZ, G. Skill, Corsair
PSU: PC P&C, Corsair (high end models), SeaSonic, OCZ
Hard-Drive: Western Digital (personal opinion, some are dead set on Seagate)
CPU is going to depend on if you went Intel or AMD. Either AM3/+ or i5/7.
Case, get enough air-flow and you're fine. Make sure Form Factors match on the case and motherboard.
DVD Drive, most anything will be fine, get a high-rated ASUS or something and you're set.
Anything you want to add-in is your own choice; Fan controllers, LEDs, Sound-Card, etc.
If you want specific parts suggested then you'd be better off in Hard-ware Forum. I would need time to come up with a list, and it will always, always be a war between who thinks what's the best. I don't buy the best due to money, I buy what I can afford and runs well.
