Monero Mining - Buying new CPUs for Old PCs

[bitstomake]

Hello,

I have access to a lot of old PCs - small form factor Lenovo ThinkCentre M91p's specifically.

Heres the model in question: http://microdream.co.uk/lenovo-thinkcentre-m91p-sff-quad-core-i5-2400-8gb-ram-250gb-windows-10-professional-64bit-desktop-pc-computer.html?gclid=COrb8NuC6M4CFe0y0wodqPIB4w#.V8Tl0FsrLIU

Is it possible to buy powerful CPUs for these older PCs, install them and start mining monero coins this way?  If so, whats the most powerful CPU that will fit in these older PCs?

Heres a list I found of the most powerful CPUs for monero mining: https://docs.google.com/spreadsheets/d/1MI-ic0Os25hgGUImW54sUIjZY_pUNQNa_W8Se5pRGBs/edit?pli=1#gid=0

If this is not possible, is there any way of putting these older PCs to use for monero mining?

Thanks

Well that is a sandy bridge second gen CPU in it by default. I believe that most sandy bridge motherboards can run ivy bridge CPU's so you should be able to stuff some LGA 1155 Ivy Bridge i7's

I am not familiar with hash rates. If you can verify the motherboard model you can verify what CPU it can take.

Small Form Factor (sff) Pc's are not conducive for GPU mining, simply because they don't accommodate any standard/large size GPU cards. Depending on the size of the lenovo sff pc you've got, they won't fit any vid cards except the low rise vid cards which won't be the cards you want to run for monero or other crypto mining. Your best bet is a ATX size, at lease medium size, PC cases, not SFF.

sockets must be compatible also you need to add related cpu microcode to bios
