Well for £100 you'll be looking at a second-hand Core 2 Quad.
Q6600 is probably the way to go to be honest.
In all honesty though, £100 is nothing.
Well, I use it mainly as a NAS, so don't want to spend much on upgrading it (cost me ~£150).
Say £100ish.
Im amazed how long the Q6600 has been going for. I had one once and ran it for a while. I know people still swear by them and are only just making to move to i5 based setups.
Will a new mobo etc even fit in a Dell case? If it's anything like the ones I used to work on, you won't be able to upgrade anything beyond the RAM :/
How cheap is DDR2 RAM? I got 8gb of DD3 for circa 30-40 quid, on ebuyer
