is there any way to move to videos/audio that you make 100% yourself, so that we can run our current systems through the same tests? i'm assuming there are a number of people here who would live to bench their system against these to see what an upgrade would cost them.
also, on the optical drive front, i see no reason not to include one.
if you want to talk music, depending on the band, its cheaper to buy used cd's than it is to buy the songs individually, and its far cheaper to buy a used dvd/bluray than to even rent a movie or tv series, some exceptions can be made if you have netflix dvd/bluray delivery, but even than, a 4 disc or 6 disc season would cost you something like 5-8$ to rent and likely the same to buy and have it shipped for free.
personally, i have a bluray burner that i use quite a bit, and i have a dvd drive that till it broke was almost constantly used... its hooked up to an IDE cable, and the last time i messed with one of those the computer wouldn't go passed the bios anymore... so i dont take it out just because i dont want my computer to screw up in a way i dont know how to fix...
lets also say you want to legitimately buy games, you can get in box on the pc games for cheaper than digital most of the time, and when a game goes on sale digitally, you can get them used on the pc for cheaper, though you probably won't line up with the eula if you go that route.
i would at the very least love to see a drive bay case in all builds like this, but the drive itself does not need to be there, a decent compromise or in the case of you absolutely do not want to have an internal drive space, than make an annotated price that shows what it would cost to hook one up... i believe an external sata ide interface is able to run dvd/bluray drives along with hdds (i had to get one when 2 of my external drive cases failed on me, cheaper getting one 20$ thing opposed to 2 cases, one for each interface.
