Which used Xeon processor to choose for LGA775 conversion?

Question

Processors

Good day to all!
I see that recently (or a long time ago, I'm just behind the times) a popular topic is the purchase of used Xeon server processors, sawing and installation in an LGA775 Socket on a home PC through an adapter.
The point is: for the last couple of years I have been working on a laptop, my PC did not even turn on (it is physically far from me). Faced with the fact that you need to carry out some calculations (math packages, compilation, etc.) and you need to uncover your stationary, because a pretty good laptop dulls, and even heats up mercilessly.
In the desktop, I now have an Intel Q6600, which is generally not bad, and even up to 3.6Ghz it is quietly chasing with normal (even air) cooling. But cooling costs several times more than a used Xeon (10-40 bucks, depending on the model).
So I want to consult whether it is worth putting it on myself, and if so, which model in terms of price / quality ratio is better to choose?
The computer will always have SSH, 5-6 users will periodically access files via SFTP, there will be a Prosody XMPP server (up to 20 users), possibly OpenVPN and Apache (for internal tests). And on the same machine, at the same time, I will run my calculations and compile the code.

Answer 1

Find out first if your motherboard is able to start up with xeon based on reviews from other experimenters or if there are any successful reviews of related boards.
Then see if there is a reason.
Q6600 under overclocking to 3.6 GHz, I remember, eats about 200 watts.
Senior Xeon under LGA771: ark.intel.com/products/36893/Intel-Xeon-Processor-... eats 150W according to the passport. That is, decent cooling is also required. This is already Penryn, not Conroe, and more cache, but this will not give much performance.
On xeon it is very joyful to move from dual-core and, especially, single-core. And from a decent 4-core - to be honest, I just don’t see the point.
If the question is power consumption, then look for Xeon L5xxx

Answer 2

I advise you to take the e5450 and not think if your mat. the board supports this processor. Firmware for bios is here - ideafix.name
