Use the filters on the side to only look at those 3 types.
Could get plenty of machine for 539 - 25% = ~404 before tax/shipping (shipping is usually free).
You'd have to drop in an SSD on your own afterwards but could get that for 90bucks or so and have it be big enough. Probably won't need to add more ram but easily could and still stay in budget (6gb is the absolute minimum I'd run in my own system, 8gb would be better. 4gb will run like dogcrap but you can easily upgrade yourself).
Intel HD built-in graphics is crap but should be fine for EQ.
Edit:
Additionally, its the outlet and the stuff they sell are either returns or refurbs so they're just looking to make some money back. If you find something you want and those coupons don't work you can add it to cart, use the 'chat with customer service' button and then tell the guy 'Hey, I'm wanting to buy blah but could you help me out on price?' Pretty easy to get a 20-25% off coupon that way. If the guy says sure! If you buy Norton or some crap, say no thanks. Empty your cart, add it again, chat again and you'll most likely get another rep. Ask them the same question.
Eventually one of them will get you a coupon with no strings attached.
