Bought new parts, is it okay to test old parts in it?

[Fayler]

I obtained parts to build a new system today with the ability to swap in a few parts of old system that went bottoms up after some sort of short or other malfunction that left me unable to boot up after some mishap involving a new case fan.

I wanted to test the old CPU (components will be listed) in the new motherboard and "lay" the old cooler on top of it just to see if the system will boot up. I am not sure if this is a dangerous idea or ,if the old CPU is damaged, if this will damage the new motherboard. I was also going to put in the old ram and HDD to see if they are salvageable.

Any input, insight, or advice is very appreciated.

Old System:
Mobo:MSI P67A-C43 (B3) LGA 1155 Intel P67
CPU: I5-2500K
GPU:SAPPHIRE 100314-3L Radeon HD 6870 1GB
RAM: 2x G.SKILL Sniper 4GB
PSU: OCZ Fatal1ty 550W Modular Power Supply
HDD: WD Black Caviar 1 TB SATA

New System:
Mobo: MSI H61M-P21 B3
CPU: I3-2120
GPU: MSI 550 GTX TI
RAM: 2x 4 gig Kingston 1333
PSU: Antec EarthWatts 650 Watt
SSD: Patriot Pyro 60 gig

Thank you in advance! If you need any more information I will attempt to provide you with it as quickly as possible.

It should be okay to test the old cpu, but not in the way you suggested. I would make sure that you do it with thermal paste and everything tightened down as if it were a full install. This way you don't break your i5 just seeing if it was broken already. I do not think there would be any issues with testing the old ram and HDD in the new system, they'll either work or not.

All those parts are interchangeable. Testing the CPU without mounting the heatsink properly (thermal paste, clamping it down, etc) will NOT work - CPUs get very hot very fast.
