thats not entierly true although dell and HP do it , there are many systems you can get that don't require you to use specific brands of hardware ,
IBM for instance supply hardware but they don't force you to have to use theres
as far as the waranty goes end users are not allowed to install hardware at all if they don't want to effect thier warranty , the exception is if you have an arangement with your supplier or manufacturer, in the case of both ibm and dell you simply have to apply to become a listed technician
Actually Pure - that's entirely true, unless I misunderstood what you're saying.
An "Open PC" which I believe you're referring to (in terms of non-specific hardware brands), is not made and assembled by a single manufacturer, but normally would be done by a retail PC shop. Even the lesser-known PC mass-producers (Ocktek for instance, when they were around) require some sort of Standard-Operating-Environment complying within their Hardware-Compatability Lists etc..
IBM will force you to use their hardware providing you're buying one of their "branded" systems - if you're buying individual IBM componentry (i.e. CPU's, NICs, etc etc...) then you would be expected to be an OEM yourself.
I have alot of info around hardware manfacturers if you're interested, including I believe the due-diligence done by IBM when they were tendering for NCS's (Division of NAB) supply-contract.
But yeah, what I said is a fact, if you buy a "Manufactured/Branded" PC from someone other than a local computer builder, you WILL be expected to comply with hardware-compatability-lists et al otherwise your warranty/service-contracts etc, etc.. are void. This is even more evident when dealing with laptops and pre-build server systems etc.
You can always buy an "Intel Certified" (also known as an "Intel Whitebox") server which doesn't lock you into a single manufacturer, but even they have a list of certified hardware with which you have to remain compliant.
Not having a go or anything, just spreading the knowledge around
