In 7 years of building computers, I've never set any hard drives in RAID. Only used one, or two as mentioned in the same exact setup as rojo mentioned. 80% of my parts came from Newegg, with TigerDirect being a close second. Love both of them, and never had any problems with either.
River, your setup is absolutely gorgeous. I'm jealous.

. Since I have to keep being reminded that a good junk of us are geeks, I have a little project that should be done by the end of this weekend. Geeks should love this. I'm transforming my Macbook Air into a very decent gaming laptop thru an external egpu (Nivida GTX760). Hopefully Ill post some pics on the off-topic sub if everything goes according to planning.

PS- Rojo, you gonna love this
