picking up server vendor in a global scope..

Hey, Let's say you want to pick a server vendor and you don't necessarily want to buy from one country and ship it to 50 different locations but instead buy them locally in each country, and also have local parties provide support. If you were to compare brands such as Dell, IBM, HP, Supermicro (or any other vendor?) which one you would recommend for this kind of approach? The server specs are fairly standard. Nothing extraordinary.. and expected support isn't also 7/24/365 but a decent next day -5 hours M- F type of deal.. thanks for responses.. Mehmet
