Okay so the servers 500GB now only has 4GB left and it is running at less than 2MB/s. It only has IDE so the limit would be a 500GB HDD, and I haven't got the case room to put a SATA adapter in and get a SATA HD. As you can see, it isn't very powerful but does the job. And with a 60% electricity bill rise floating around in Australia, I would like to be very eco-friendly. I was looking at another ITX build, simply for the low power and size factors, however I can't for the life of me find a decent ITX case with a good PSU and at least 2x3.5" drives. I have been looking at chucking my current G33M-S2H into an Antec NSK 1380 or Antec NSK 2480. If I pair that up with an e2180 and 2-3GB of RAM, it shouldn't use that much more power than my current server, esp with the 80% PSU. (Then upgrading the G33M-S2H computer to an i3) The current problems I am having at the moment are the hard drives. The primary objective of this server is to be a file/backup server. All the computers in the house back up to this computer so a reliable hard drive is vital. I want the hard drive to be fast, but reliability is key. I have been a bit skeptical of hard drive recently as I have had two incidents where the hard drive works, someone backs all their stuff onto it and then when they power it on for the second/third time it is just completely dead. So I have been looking at a few options. I'm considering getting 3x1TB HD's in RAID 5, a quick 500GB HD (or two in RAID0) and secondary 1.5-2TB HD OR just 1x1TB HD. As I said I need reliablity, but I do transfer lots of large file on and off the server, so I need fast drives. The problem with most of the above options is at the moment I can only really afford 1 HD (Two, depending on the size, however pointless as they won't be in RAID0 or 1) I have been looking at WD blacks but have never personally used them, so unsure of what they have to offer. So the HD's are my primary concern. The other thing is back to the m-ITX vs m-ATX. I was leaning towards the 3x1TB drives in RAID 5 originally which is why I couldn't find a decent mITX case. I might now, however, change that. Thing is, I do already have the G33 board so it will be cheaper (as I was planning on putting an i3 in that PC...the quad core is doing nothing other than using power, it's better off sold), but I am only going to use 3 hard drives, on board gigabit LAN and onboard VGA....nothing required in expansion PCI slots. Which is why I think getting a mATX computer would be a waste of room (altho I can't find a mITX case that suits). Can someone shed some light on this situation? haha.
