This is my Lenovo ThinkPad R61, 15.4" sub-model 8930-A41, and I am showing you inside the machine before I upgrade the CPU from Celeron M 550 to Core 2 Duo T7500.
I bought this machine for an INSANE price of £55 + FREE shipping from eBay UK, and when it arrived, I inspected the machine, and there IS NO WEAR AT ALL on the machine OR the keyboard (there's usually shine-wear on the keys, but this is MINT!). When I took the machine apart today, to upgrade the CPU, I discovered NO DUST WHATSOEVER, **ANYWHERE**, not even on the heatsink/heatpipe ass'y OR on the fan or fan blades - NO wear, no dust, ANYWHERE!
The only thing which makes this machine non-mint, is that the seller - a PC recycling company, had to sand off the corporate logo from the lid, but since that's only a small strip, bang in the middle of the lid, I can just put a large sticker over it, or if I was fussy, buy a mint lid from eBay for around £15-20.
Enjoy the video! Oh, and I mentioned I'd come back and show you inside once the CPU upgrade was done, but I didn't, sorry!
