The only problem I see is the server is slightly an older HP ProLiant but will have dual 2.66 GHZ Xeons with 12MB L2 cache and 8gb of PC2-5300 Fully Buffered DIMMs (DDR2-667).
It's got dual power supplies also, that's the creepy thing, but will offer hot swaps on the HDDs.
The problem is, I hear of no-one I know run Xeons anymore. The last time I had a setup like this, they were dual 600mhz possible up to quad processors but this was also when 1ghz processors were the norm on the market.
I know persons who still use xeons, your luck is you can still throw a half decent card in that board as it should have pci-e 2.0 for the age.
You should be able to find faster ram if the board supports it though, I used less hardware with two dual display nvidia business cards and ran 3 monitors fine, rarely played video and definitely not games though, but it was for work and did that great. (was at work too). A HP dc7900 SFF.
