Hello bit-tech. I'm in a quandary, I have a bond that's matured and with interest rates the way they are I'd rather spend the money then to break my back and receive 3% extra back after a year or so and insipred by this thread I thought I'd get a new NAS. The question is do I spend my money on a prebuilt NAS or DIY it, currently I have a hacked MBWE which does the job if a little slowly and has a tenancy to crash if I ask too much of it. If you're up for the challenge I need some help evaluating my choices, here is a pretty table of my current costing: Best case is based on the fact I have a box under my bed full of random computer bits and the NIL bits are from a failed HTPC that never took off as I dont have a nice HDTV to call my own. However I may have sold/cannibalised many of these parts over the course of time so the NIL cost parts may become expensive. Here is a quick list of the core features I think each system has and that I would need: *Problem? The pretty pics so you visualise what I'm talking about: Chenbro (DIY) QNAP You'll notice that I haven't mention storage HDDs anywhere, that's because I was planning on stuffing the cases with 4 x Samsung F2 1.5 TB as they have the best price per GB atm, the low power is a bonus to a NAS and some of the performance issues should be mitigated by the RAID 5. If any of my reasoning if flawed please point it out as that's why I'm posting here Also if any links are required, please say and I'll post them.
