What to buy

Before I start asking for quotes I need to decide what to buy! So .....

Has anyone recently bought computers, mini tower, dual core, 2gb min ram, windows 7 pro/xp pro? 3 year onsite warranty. Looking to buy about 22 in two batches 0f 11 - 6 months apart.

I'm torn between branded and non branded, the computers I'm replacing which will be cascaded into classrooms, were from a local shop which then joined forces with a large company and moved 100 miles away, are non branded with my choice of sturdy case and 'bogstandard' parts, so far trouble free (touching wood!) so I can't decide.

@chrbb:

Just PM'd you :)
