Conclusion: In the cutthroat world of budget PCs, it's hard to stand out from the pack. After all, there's only so much an OEM can deliver for around $500. There's a lot to like about the C540, first and foremost the beautiful screen. But if you are shopping on price, be sure to check the competing all-in-ones from HP, Acer, and Gateway. You might find one with slightly better specs at a similar price.
