Trying to find the Swiftech MCP655 pump.

[MadMinute]

Im looking at building a new PC cooling system and im trying to find all the parts i need. After hours of research I decided to go with the Swiftech MCP655 pump however ive run into an issue. The problem is it has multiple names. This has me confused. I have found that the pump is called the Swiftech MCP655, Laing D5 Vario, and PMP-450. So far multiple searches have yielded very little results. I was unable to find a pump for sale under the name Swiftech MCP655(newegg no longer carries it). However, i have found 1 for sale under the name of Laing which was about $100. And i also found koolance selling the PMP-450 for about $75. Can someone please tell me the difference between these pumps and where i can find the cheapest one? Also, any other names for the same pump.
Feel free to give me your opinion if you think i should not go with this pump and what pump i should get instead.
Im trying to get a pump that is reliable and quiet. It will cool my cpu, gpu and potentially my ram(though that would be for cosmetic purposes).
Pump size is no issue as im using the Obsidian 900D.
Thanks

All of those pumps are the Laing D5. Companies like swiftech and Koolance sell their own versions, but the pump motors are all manufactured by Laing. Here is a link to the FrozenCPU page with some of your options.

Basically, any of those will work, but if you get one of the bare pumps, you will need to purchase a top separately.

I guess i had that wrong, thanks for letting me know. The link has a bunch of the pumps, are any of them in any way the best? Aslo, are they any better than the $75 one by koolance here: http://koolance.com/pmp-450-pump-id-13mm-1-2in

All of the D5 pumps are going to perform very similarly, I can't say I've heard anything good or bad about the Koolance one. If you go with that one you're going to want to get a top also. Any of these will be compatible:

Basically the top screws onto the pump and then you connect your compression fittings or barbs to the top.

Is the top required or is it just recommended? I did not realize i might need one.

It's not required, but it will improve your flow and allow you to use G1/4 fittings instead of having to connect the hoses directly to the pump with clamps.

Thank you for the help and the quick replies.
