I'm looking for input on a NAS setup, my main requirements are:

* 4 drive bays (more is OK, but 4 is probably what I need, any less is no good).

* Wireless, so I can shove it in a closet somewhere and forget about it.

* RAID 5

* Ease of use and setup.

Anyone have any advice?

Checkout Synology's units, very good and reliable.

I will do that right now, thank you. Any other suggestions and opinion would be useful too.

Keep in mind that you'll need a wireless bridge to your NAS if you want it barebone, you could also build one with is cheaper but it kinda fails when it comes to "easy to use" compared to pre-built.

Yeah, I figured. I don't understand why so few of these products don't have wifi by default.

I actually have all almost all the parts (just missing a wifi card and a few more hard drives) to build one myself, but ugh, I don't have the time or inclination to do it really, especially if it ends up being more hassle in the long wrong when I need to replace drives and such.

I was looking at Synology's CS407e, CS407 and CS408 but there doesn't seem to be any discernable reason for me as to why one would be better than the other. Presumably I should just get the cheapest, since I don't need any of the functions like web hosting, php, ajax, IP camera access, etc. Or would one of these models be more suitable for my needs (mainly just accessing multimedia files to view from my PC and laptop)?

CS407 and CS408 have a lot faster CPU (faster in general than 407e), CS408 (800Mhz + 512Mb RAM) is faster than CS407 (500Mhz + 128Mb) too.
