A lot of sellers (so far I've only been looking at top rated sellers) say they have no gurantee on battery life, other than that it works. Are genuine replacement batteries available from Lenovo themselves?

I want/need a portable machine for an upcoming project, and because I spent a lot of money already on my gaming rig, I wanted something cheap. I found out that eBay is full of used old ThinkPads, and they seemed really fun to work with. I looked at the ThinkPad subreddit and people were really modding theirs to perfection, and while I will not initially plan on upgrading, I might eventually swap the TN panel for a FHD IPS panel. I am planning on carrying it outside every day in a backpack, and both the T series and X series seemed to suit me well. What are the differences between the two? Most listings on eBay were the T420 ~ T450, including variants. For under $200 without upgrades, what is the best used ThinkPad?

I would most likely buy a pump/res combo, so everything would be alright? I'm probably going to do single bends and fittings for the rest.

Hello, I currently own a system that I did not spend money on cooling at all (box cooler). I had the idea of a custom loop in mind from the beginning, but now that it's getting warmer I thought it would be a nice time to upgrade. I will be cooling my 2600X as well as my Strix 2070 OC, and everything from EKWB (at the moment). My chassis is the Corsair Carbide 275R. I realized that this case was a bit cramped for a custom loop (definitely not designed for it), so I took measurements carefully. The picture below is the *fantastic* prototype sketch made in Google Drawing. In this config, everything seems to be fitting well. I will be attempting hard tubing (would love tips on how to do multi-bend tubes) as well. Do you see potential issues making this loop? The drain valve is connected to the reservoir (black square with a circle), so that everything can be drained when turned upside down (if that's possible). I'm really excited for this one and I need your help to not make dumb and expensive mistakes. Thanks in advance!? Also: How much extra tubing should I buy in case I make bad bends? What coolant is the best? (not settling on colored ones because apparently they gunk up?) Put some pics of the case for size (measurements in centimeters)

Now, I know there are duplicates, but just HOW FAR can I push my Corsair Vengeance 2666Mhz 8GBx2 RAM? (without dedicated cooling)
