I was planning on building a new 64-bit server for the house, as I've got a spare mother board and an Intel CoreDuo processor to hand, along with the appropriate server OS licenses. We're planning on upgrading from our current little AMD-powered server to something with a bit more poke, and also want to use eSATA for a backup drive. As a result I've been pricing up cases, power supplies, and memory.
The bits I needed were going to come in at around £200 or so. Not too bad for a server, I thought. Then I found an advert in PC Pro, for a company advertising an OS-less HP server for less than 180 quid including VAT. If I look at the cost to me of my time, and the cost of the bits I need to finish my box, the decision turns out to be something of a no-brainer. There's no way I can build a box for that price.
We've ordered the machine (which also turns out to be a dual core Xeon), and sprung for an additional pile of memory via Crucial (the HP prices for memory were rather silly).
Free delivery too, even if I do have to wait a week...
I think that motherboard will now end up as my next desktop PC.
