And why would you pay $499 when you can get 360 addon for $160 after coupon? (although I've heard they don't respect their $40 coupons anymore so it is $199). Still $299 difference, almost good for A1.
360 addon can be installed internally with 2.5 to 3.5 $5 IDE adaptor from eBay.
People have done it and succeeded.
