can anyone tell me what is the difference between secc and aluminium chassis?
Do they differs in the sense of lightness and heat rejection capacity?

In terms of weight, yes.
Aluminium casings are alot lighter than SECC casings.

In terms of heat dissipations, in a little way, yes Aluminium casings does help in dissipating heat, but not by much, just a little.

alu case does not help in heat dissipation as the case does not come into direct contact with the heat producing component unlike heatsinks...the only thing that the case has as a heat conductor from those components would be air... and air can be said to be one of the worst heat conductor.

it is the design of the case that helps with heat dissipation...not the material.

Which one does people prefer nowadays? Budget does comes first, but which one is more preferable? SECC or aluminium casing? As for heatsinks, do shops sells em?

i'd go for Aluminium , SECC it's just too heavy

most people prefer aluminium...main reason is the weight.. next reason is because they look uber sexy.

as for heatsinks, yes, shops sell them...but also depends on what heatsink u want.

is it expensive?? have you tried installing the heat sink before?

wat heatsink are u talking about in the first place?

i was talking about aftermarket heatsinks for CPUs, graphics card etc..

but in terms of heatsink, copper is a better material. ur CPU, graphics card, motherboard should already have heatsinks on them.

Better go for alu casee if u decide to bring it anywhere..i mean to a lan party ..Go for SECC if u plan to stick ur pc at home only..
But for starer,go for Lian li-its very cheap..

actually i was reffering to the heat sinks which can be installed manually into the cpu such as the fan etc.probably i sound silly .is it available?

aftermarket heatsink la.... yes its available... low yat plaza has alot of them.

get those motherboard which has copper pipeline that can dissipate heat even more efficiently like the latest asus board

Those motherboard that has those heatpipes has worse heat dissipation if you compare to those that doesn't have heatpipe.
Tested and verified.

those heat pipes might work sometime just might not work, all depends on where u place ur mobo...........

so far i only found heat pipes for mother boards really works good on PWM only, others more or less about the same no point

Depends on your case ventilation & the position of the components. If you have even ONE case fan (or have a decent PSU fan), then it unlikely you'll notice any difference. Which in that case you do have a good point, since most PCs today have case fans, so yes, there is negligible difference.

SECC aka steel is usually cheaper, but it varies from manufacturer.

Lian-Li and cheap. Two words that usually don't end up in the same sentence unless its in the negative..

As all we know alluminium material not heavy
from other material like steel.

yeaps..alu is lighter than secc(steel) and has better heat disipation tho more preferable....

Since you have the answer to your question now, then this thread should be closed already.
