PLEASE delete the western digital velociraptor from the list. Waste of money. A good WD black edition 1gb or samsung spinpoint 1gb are as fast and have way more storage. You already have a ssd hdd for OS anyway (albeit far too small) spend less money on the 3.5 hard drive and more on the solid state for more capacity. 250gb is the minimum I would have for my main drive. Also, if its just photoshop your using, not gaming, that gfx card is overkill. A GT240 or something is good enough, will also save you some money.
Thanks. Good points.
