I recently bought an old 360 because it had a really old dashboard and was dirt cheap. This particular unit was still sealed (had the microsoft warranty sticker) and works just fine. But after opening it up, I couldn't help but notice 8 blown nichicon hzs (0601) right by the cpu heatsink and 2 blown kzjs. Should I replace them and if so, what kind of capacitors should I order?

Re: Xbox 360 blown caps
Replace with electrolytic capacitors that are very low ESR (Panasonic FM/FR , UCC KZE series) or polymer capacitors.
In the case of the capacitors closest to chips (output of VRM) it's safe to use polymer capacitors rated for lower voltage... for example you know the output of a VRM (dc-dc converter) is less than 2v but they've used 6.3v rated electrolytic capacitors for several reasons... you can safely use cheaper 4v rated polymer capacitors with same capacitance or 10-20% less capacitance (ex you could use a 1200uF 4v instead of 1500uF 6.3v if 1500uF is hard to find or doesn't fit)
Here's a pre-filtered list of electrolytic capacitors, series that would be suitable .. just pick capacitance and voltage then pick highest ripple current and lowest esr and right distance between pins and diameter) : https://www.digikey.com/short/pb8r0b
Here's a starting point for polymer capacitors : https://www.digikey.com/short/pb8rv5
