I have an opportunity to pick up a used HP DL380 G3 2U for $100. I'm looking for a basic entry level web server that I can host a small - medium size website on and more or less learn the ins and outs of running my own web server before I bite the bullet and spend a couple grand on a server. The specs are:

• Dual (2) Intel Xeon 2.4GHz 400MHz 512KB Cache
• 4GB PC2100 ECC Registered Memory
• 6 x 72GB 10K U320 SCSI Hard Drives
• Smart Array 5i RAID Controller
• Redundant Power Supplies
• DVD/Floppy, Dual Intel GB NIC's, USB

Or would I be better off spending a couple hundred bucks on something like: this new HP Seems like the only major difference is SATA and a bit of storage, but I will likely be implementing a separate storage system of some sort anyways.

I guess it also wouldn't hurt to mention that I plan on running a linux server distro, so would the hardware be likely to support linux with a system that is 4 generations old? I don't mind spending a couple hundred extra dollars if its a better solution, but as mentioned previously I am simple looking for a server to learn on and probably use for a year or so while I put together a small - medium size website.
