I've had a home server that's been running remarkably well, considering the loads I put on it. But I think it's time to upgrade, as software updates seem to have made it a little slow, there are limitations such as the number of SATA ports and external connectivity - and there is the nagging worry that the components are near the end of their lifetime(s).
Conditions for the upgrade:
Must come to a grand total of less than £120
Motherboard must be micro-ATX (or less I suppose)
Motherboard must be either eSATA or USB3 (preferably eSATA) compatible, as I would probably, in the future, want to get an external backup drive.
The server runs 24/7, running Apache with a few PHP/MySQL websites, samba file server, public Minecraft server
Power consumption is a major concern. If at all possible, I would not like to raise this. Electric prices can only go up in the long run, and I've measured it to use 50-60W on average as it is now.
Graphics is, as you would imagine, not of interest. I do of course need basic integrated graphics in order to run a console for maintenance (server's headless when operational).
Gigabit Ethernet would be very nice for a future in which I have a gigabit capable router.
The current components, with those to be upgraded in bold, are:
CPU: AMD Athlon 1600-LE (single core, 2.2GHz) [surprised it doesn't grind to a halt at times] Mobo: Gbyte M61PME-S2 [I think anyway] (nForce 430, 2x SATAII, AM2) RAM: 4GB DDR2 800MHz
PSU: Corsair CX400 (400W rated, possibly slightly lower due to capacitor fatigue, about a year of 24/7 usage so far, hasn't skipped a beat though)
HDDs: 2x 1TB SATAII Western Digital Greens
MicroATX case (v. cheap one, but not going to upgrade. Has an 80mm fan at the back)
Here are some Intel components that I'm considering:
Asus P8H61-M LE/USB3, H61 sandy bridge chipset (£47.97)
Any option would also include either 4 or 8GB of DDR3 1066/1333 memory. I've seen Corsair dual module kits for £20.09 and £35.99 respectively. What do you reckon about the reliability of those, considering the price? (I could probably spend a little more than £120 if absolutely necessary).
The operating system is Debian 6 Linux, so as a separate question, if you know anything about this issue, what would be the chances of simply swapping out the old mobo/CPU/RAM and putting the new stuff in, and have everything "just work" (well, I don't mind reconfiguring network devices and the fstab, but after that, I mean). I really don't want to have to shift all the data off the huge hard drive and put it all back piecemeal.
