I have two old computers that I'm using for servers. Both are running Ubuntu 10.04 Server 32-bit since each only have 2GB of DDR RAM. They run off of Intel Pentium 4 2.4Ghz single core processors. I've been able to turn one into a Minecraft server for three people and for the most part it runs pretty well. But I'm looking to upgrade.
So I'm wondering what I should put into the system. There are a few routes I can go. One of them is to build a completely new system. I would plan on going with an Intel desktop processor for the server and I would probably stick with cheap parts that aren't really needed for Minecraft to be fast. From what I know 2GB of RAM and a fairly fast is good for Minecraft. I'll only have a few users online at a time since it will just be a private server with some friends. So a max of 5 people should ever be on at a time. So I'm asking you for any suggestions on processors and other components for the server.
As for the other route I could go is by upgrading my desktop machine and using the old parts for the server. My desktop was built earlier this year and has 4GB of RAM and a 2500K processor. I would probably buy whatever Intel processor is better than the 2500K next year and then use the 2500K and motherboard if Intel changes the socket for the server. If not I'll use the 2500K and buy a new motherboard and new RAM.
So I'm wondering what exactly I should do for this server. Build a new server or use older parts. I'm looking for what would be best for my money.
I built a system about a month ago with 16GB of RAM and a Core i3-2120 processor. The machine is running ESXi 5.0 and I setup a Server 2008 R2 VM for the Minecraft serer and it works great with 5GB of RAM.
Now I just need to get a better internet connection at least as far as upload speed goes for the server.

Don't waste money on a fancy Processor, Maybe a Pentium Dual core Nothing more than an Intel i2 if you don't have Fibre Internet with a decent up/downstream. Definitely increase the RAM though, No more than 8GB though, this is because although Hardware-wise, your server may be good, Your Internet connection can't always handle it. ADSL - You're Pushing Your Luck, FTTC - Reliable enough to handle it, FTTP/H - If You're gunna overdo it :P

I don't know how you can use that much RAM. When I was runnnig a server with a large map and 30+ plugins I was using less than a Gig of RAM. The most important part is definitely your internet connection.

You'll ruin your SSDs with a minecraft server, I recommend using Ramdisk to host the world to help preserve your SSD(s). As for 15 players, I have 40+ plugins, a few of them being Spout, SpoutEssentials, an orebfuscator. I never have more than 300mb used with one player on. That's using Bukkit and not having ramdisk setup. If your just running vanilla server you would be more than fine with 4GB for 15 players. I recommending not trusting canihostaminecraftserver.com AT ALL. It's really inaccurate. I recommend setting up a temporary server and seeing how much memory/internet you actually use. Then basing it off of that whether or not you need something better. In console while using Bukkit, it might throw you the "Did the time change or is the server overloaded?" message. It's really not. If you tell the Java process to use almost all of your memory it's going to think your out when you're really not. There's really no definitive answer to this.

If I'm brutally honest, you could have the best server in the world and it would never run well. We have our server running on a 1Gbps connection and there are still times when under load it's a little bit slow.
Your best option would be to host on a VPS. Currently we pay $60 a month and we run an i7 with 16GB of RAM and 2TB hard drive space.
Those specifications may be a bit overkill to start with on a small server but there are lots of other lower end packages for less.
