Hi there BorisTheAnimal,

Have you maybe forgotten the question?
Sorry if i'm missing something but you have mentioned you want to computer advice and told us you have 3 computers and what the specifications are.

What advice do you want?

Regards,
Jamie

Well I did however say that n.1+2 were only standing in my room collecting dust but it seems it was not specific enough, sorry about that.

Basically, is there a market value for my goods? Or should I build something, like a NAS server?

Your computer number 1 will bottleneck crossfired HD 7870 and will still bottleneck a single 7870. Go with something a little bit lower to par with the A4-5300.

Thanks for the advice, though this is not a shopping cart, I own these items so um yup.

To sell it as a system if you aren't including an OS I would say you could get about 200 on ebay for those if that. Maybe add a little more if you have a legit OS going with it.

You may be able to take them apart and sell them as parts and make a decent amount of money assuming they are clean and in good working order.

Explain how can it bottleneck?

Your CPU came with AMD Radeon 7480d graphics card. Are you sure you have two 7870's? The 7480d is a lower end graphics card and would be the bottleneck if in fact you had it "crossfired" with a 7870, which is a higher end graphics card.

Since you are selling it, this really doesn't matter to you but either way, I doubt anyone is in the market for either of your first two PC's unless its for cheap. #1 would make you more money in parts for sure.

Yes I'm quite sure of it because one of the cards only have one fan but on the other there are two fans, and yeah forgot about the integrated graphics.

So now that you have explained and I have seen you have some superior knowledge of the market, could you give me like some advices on what price amounts I can put on the different parts?
